## - Don't want to use -MD because we'd like the dependencies to end
## up in a subdir. Having to rename by hand is ugly.
## (We might end up doing this anyway to support other compilers.)
## - The DEPENDENCIES_OUTPUT environment variable makes gcc act like
## -MM, not -M (despite what the docs say). Also, it might not be
## supported by the other compilers which use the 'gcc' depmode.
## - Using -M directly means running the compiler twice (even worse
## than renaming).

## This next piece of magic avoids the "deleted header file" problem.
## The problem is that when a header file which appears in a .P file
## is deleted, the dependency causes make to die (because there is
## typically no way to rebuild the header). We avoid this by adding
## dummy dependencies for each header file. Too bad gcc doesn't do
## this for us directly.
## Some versions of gcc put a space before the ':'. On the theory
## that the space means something, we add a space to the output as
## well. hp depmode also adds that space, but also prefixes the VPATH
## to the object. Take care to not repeat it in the output.
## Some versions of the HPUX 10.20 sed can't process this invocation
## correctly. Breaking it into two sed invocations is a workaround.

\`configure' configures putty 0.76 to adapt to many kinds of systems.
Usage: $0 [OPTION]... [VAR=VALUE]...
To assign environment variables (e.g., CC, CFLAGS...), specify them as
VAR=VALUE. See below for descriptions of some of the useful variables.
Defaults for the options are specified in brackets.
Configuration:
-h, --help display this help and exit
--help=short display options specific to this package
--help=recursive display the short help of all the included packages
-V, --version display version information and exit
-q, --quiet, --silent do not print \`checking ...' messages
--cache-file=FILE cache test results in FILE [disabled]
-C, --config-cache alias for \`--cache-file=config.cache'
-n, --no-create do not create output files
--srcdir=DIR find the sources in DIR [configure dir or \`..']
Installation directories:
--prefix=PREFIX install architecture-independent files in PREFIX
[$ac_default_prefix]
--exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
[PREFIX]
By default, \`make install' will install all the files in
\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
an installation prefix other than \`$ac_default_prefix' using \`--prefix',
for instance \`--prefix=\$HOME'.
For better control, use the options below.
Fine tuning of the installation directories:
--bindir=DIR user executables [EPREFIX/bin]
--sbindir=DIR system admin executables [EPREFIX/sbin]
--libexecdir=DIR program executables [EPREFIX/libexec]
--sysconfdir=DIR read-only single-machine data [PREFIX/etc]
--sharedstatedir=DIR modifiable architecture-independent data [PREFIX/com]
--localstatedir=DIR modifiable single-machine data [PREFIX/var]
--runstatedir=DIR modifiable per-process data [LOCALSTATEDIR/run]
--libdir=DIR object code libraries [EPREFIX/lib]
--includedir=DIR C header files [PREFIX/include]
--oldincludedir=DIR C header files for non-gcc [/usr/include]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--datadir=DIR read-only architecture-independent data [DATAROOTDIR]
--infodir=DIR info documentation [DATAROOTDIR/info]
--localedir=DIR locale-dependent data [DATAROOTDIR/locale]

Optional Features:
--disable-option-checking ignore unrecognized --enable/--with options
--disable-FEATURE do not include FEATURE (same as --enable-FEATURE=no)
--enable-FEATURE[=ARG] include FEATURE [ARG=yes]
--enable-silent-rules less verbose build output (undo: "make V=1")
--disable-silent-rules verbose build output (undo: "make V=0")
--enable-dependency-tracking
do not reject slow dependency extractors
--disable-dependency-tracking
speeds up one-time build
--enable-setuid=USER make pterm setuid to a given user
--enable-setgid=GROUP make pterm setgid to a given group
--disable-git-commit disable embedding current git HEAD in binaries
--disable-gtktest do not try to compile and run a test GTK+ program
Optional Packages:
--with-PACKAGE[=ARG] use PACKAGE [ARG=yes]
--without-PACKAGE do not use PACKAGE (same as --with-PACKAGE=no)
--without-gssapi disable GSSAPI support
--with-quartz build for the MacOS Quartz GTK back end
--with-gtk=VER specify GTK version to use (`1', `2' or `3')
--without-gtk do not use GTK (build command-line tools only)
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L if you have libraries in a
nonstandard directory
LIBS libraries to pass to the linker, e.g. -l
CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I if
you have headers in a nonstandard directory
PKG_CONFIG path to pkg-config utility
PKG_CONFIG_PATH
directories to add to pkg-config's search path
PKG_CONFIG_LIBDIR
path overriding pkg-config's built-in search path
CPP C preprocessor
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
Report bugs to the package provider.

Oops!
Your 'rm' program seems unable to run without file operands specified
on the command line, even when the '-f' option is present. This is contrary
to the behaviour of most rm programs out there, and not conforming with
the upcoming POSIX standard:
Please tell bug-automake@gnu.org about your system, including the value
of your $PATH and any error possibly output before this message. This
can help us improve future automake versions.

cat >&2 <<'END'
Aborting the configuration process, to ensure you take notice of the issue.
You can download and install GNU coreutils to get an 'rm' implementation
that behaves properly: .
If you want to complete the configuration process using your problematic
'rm' anyway, export the environment variable ACCEPT_INFERIOR_RM_PROGRAM
to "yes", and re-run configure.

#
# This file is free software; the Free Software Foundation

# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
#
# Of course, Automake must honor this variable whenever it calls a
# tool from the auxiliary directory. The problem is that $srcdir (and
# therefore $ac_aux_dir as well) can be either absolute or relative,
# depending on how configure is run. This is pretty annoying, since
# it makes $ac_aux_dir quite unusable in subdirectories: in the top
# source directory, any form will work fine, but in subdirectories a
# relative path needs to be adjusted first.
#
# $ac_aux_dir/missing
# fails when called from a subdirectory if $ac_aux_dir is relative
# $top_srcdir/$ac_aux_dir/missing
# fails if $ac_aux_dir is absolute,
# fails when called from a subdirectory in a VPATH build with
# a relative $ac_aux_dir
#
# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
# are both prefixed by $srcdir. In an in-source build this is usually
# harmless because $srcdir is '.', but things will broke when you
# start a VPATH build or use an absolute $srcdir.
#
# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
# and then we would define $MISSING as
# MISSING="\${SHELL} $am_aux_dir/missing"
# This will work as long as MISSING is not called from configure, because
# unfortunately $(top_srcdir) has no meaning in configure.
# However there are other variables, like CC, which are often used in
# configure, and could therefore not use this "fixed" $ac_aux_dir.
#
# Another solution, used here, is to always expand $ac_aux_dir to an
# absolute PATH. The drawback is that using absolute paths prevent a
# configured tree to be moved without reconfiguration.

# One issue with vendor 'install' (even GNU) is that you can't

# annoying in cross-compiling environments, where the build's strip
# is unlikely to handle the host's binaries.
# Fortunately install-sh will honor a STRIPPROG variable, so we
# always use install-sh in "make install-strip", and initialize
# STRIPPROG with the value of the STRIP variable (set by the user).

==============================================
Going into pre-release stabilisation
------------------------------------
When we begin to work towards a release and want to enable
pre-releases on the website:
- Make a branch whose tip will be the current state of the
pre-release. Regardless of whether the branch is from master or
from a prior release branch, the name of the branch must now be in
the form 'pre-X.YZ', or else the website will fail to link to it
properly in gitweb and the build script will check out the wrong
thing.
- Edit ~/adm/puttysnap.sh on my build machine to set $prerelver correctly.
- Edit ~/adm/puttysnap.sh on the master machine to enable pre-release
builds, by changing the 'if false' to 'if true'.
- Put the website into pre-release mode, by defining prerel_version()
in components/Base.mc to return the upcoming version number. Also
add a news announcement in components/news. (Previous naming
convention has been to name it in the form 'X.YZ-pre.mi'.)
Things to do during the branch-stabilisation period:
- Go through the source (including the documentation), and the
website, and review anything tagged with a comment containing the
word XXX-REVIEW-BEFORE-RELEASE. (Any such comments should state
clearly what needs to be done.)
- Do some testing of the Windows version with Minefield (you can
build a Minefield version using 'bob . XFLAGS=-DMINEFIELD'), and of
the Unix version with valgrind and/or Address Sanitiser. In
particular, any headline features for the release should get a
workout with memory checking enabled!
Making a release candidate build
--------------------------------
- Make a directory to hold all the release paraphernalia. I usually
call it ~/src/putty/X.YZ (where X.YZ will stand throughout for the
version number).
- Inside that directory, clone the PuTTY git repository to a
subdirectory ~/src/putty/X.YZ/putty. Here you can make release-
related commits and tags tentatively, and keep them out of the way
of any 'git push' you might still be doing in other checkouts.
- Double-check that we have removed anything tagged with a comment
containing the words XXX-REMOVE-BEFORE-RELEASE or
XXX-REVIEW-BEFORE-RELEASE. ('git grep XXX-RE' should only show up
hits in this file itself.)
- Now update the version numbers and the transcripts in the docs, by
checking out the release branch in the release-specific checkout
and running
./release.pl --version=X.YZ --setver
Then check that the resulting automated git commit has updated the
version number in the following places:
* putty/LATEST.VER
* putty/doc/plink.but
* putty/doc/pscp.but
and also check that it has reset the definition of 'Epoch' in
Buildscr.
- Make the release tag, pointing at the version-update commit we just
generated.
- If the release is on a branch (which I expect it generally will
be), merge that branch to master.
- Make a release-candidate build from the release tag, and put the
build.out and build.log files somewhere safe. Normally I store
these inside the ~/src/putty/X.YZ directory, alongside the git
checkout at ~/src/putty/X.YZ/putty, so I'll sit in that checkout
directory and run a command like
bob -o ../build-X.YZ-rcN.out -l ../build-X.YZ-rcN.log -c X.YZ . RELEASE=X.YZ
This should generate a basically valid release directory as
`build-X.YZ-rcN.out/putty', and provide link maps and sign.sh
alongside that.
- Double-check in build-X.YZ-rcN.log that the release was built from
the right git commit.
- Make a preliminary gpg signature, but don't run the full release-
signing procedure. (We use the presence of a full set of GPG
signatures to distinguish _abandoned_ release candidates from the
one that ended up being the release.) In the 'build.X.YZ-rcN.out'
directory, run
sh sign.sh -r -p putty
which will generate a clearsigned file called
sha512sums-preliminary.gpg _outside_ the 'putty' subdirectory.
- For my own safety, make the release candidate build read-only.
chmod -R a-w build-X.YZ-rcN.{out,log}
- Now do some checking of the release binaries, and pass them to the
rest of the team to do some as well. Do at least these things:
* make sure they basically work
* check they report the right version number
* if there's any easily observable behaviour difference between
the release branch and master, arrange to observe it
* test that the Windows installer installs successfully
+ on x86 and Arm, and test that putty.exe runs in both cases
* test that the Unix source tarball unpacks and builds
+ on at least a reasonably current stable Linux distro, and
also try Debian sid
+ test-build with all of GTK 1, 2 and 3
+ test-build with -DNOT_X_WINDOWS
* feed the release-candidate source to Coverity and make sure it
didn't turn up any last-minute problems
* make sure we have a clean run of sctest
* do some testing on a system with a completely clean slate (no
prior saved session data)
Preparing to make the release
-----------------------------
- Write a release announcement (basically a summary of the changes
since the last release). Check the draft version into the putty-aux
repository, so the whole team can help wordsmith it if they want to.
- Update the website, in a local checkout:
* Write a release file in components/releases which identifies the
new version, a section for the Changes page, and a news
announcement for the front page.
+ The one thing this can't yet contain is the release date;
that has to be put in at the last minute, when the release
goes live. Fill in 'FIXME', for the moment.
* Disable the pre-release sections of the website (if previously
enabled), by editing prerel_version() in components/Base.mc to
return undef.
- Update the wishlist, in a local checkout:
* If there are any last-minute wishlist entries (e.g. security
vulnerabilities fixed in the new release), write entries for
them.
* If any other bug fixes have been cherry-picked to the release
branch (so that the wishlist mechanism can't automatically mark
them as fixed in the new release), add appropriate Fixed-in
headers for those.
- Sign the release in full. In the `build-X.YZ-rcN.out' directory,
re-verify that the preliminary signed checksums file has a correct
signature on it and also matches the files you're about to sign for real:
gpg -d sha512sums-preliminary.gpg | (cd putty; grep -vF ' (installer version)' | grep . | sha512sum -c)
If the combined output of that pipeline reports both a good
signature (from the release key) and a successful verification of
all the sha512sums, then all is well and you can do the full
signing (not forgetting that the directory will have been readonly
during the last-minute testing period):
chmod -R u+w putty
sh sign.sh -r putty # and enter the release key passphrase
chmod -R a-w putty
The actual release procedure
----------------------------
Once all the above preparation is done and the release has been built
locally, this is the procedure for putting it up on the web.
- Make a final adjustment to your local website changes, filling in
the release date in components/releases/X.YZ.mi.
- Upload the release itself and its link maps to everywhere it needs
to be, by running this in the build-X.YZ-rcN.out directory:
../putty/release.pl --version=X.YZ --upload
- Check that downloads via version-numbered URLs all work:
../putty/release.pl --version=X.YZ --precheck
If this has trouble accessing chiark's ftp server, that is
unfortunately normal; add --no-ftp and try again.
- Switch the 'latest' links over to the new release:
* Update the HTTP redirect at the:www/putty/htaccess .
* Update the FTP symlink at chiark:ftp/putty-latest .
- Now verify that downloads via the 'latest' URLs are all redirected
correctly and work:
../putty/release.pl --version=X.YZ --postcheck
- Push all the git repositories:
* run 'git push' in the website checkout
* run 'git push' in the wishlist checkout
* push from the main PuTTY checkout. Typically this one will be
pushing both the release tag and an update to the master branch,
plus removing the pre-release branch, so you'll want some
commands along these lines:
git push origin master # update the master branch
git push origin --tags # should push the new release tag
git push origin :pre-X.YZ # delete the pre-release branch
- Run ~/adm/puttyweb.sh on thyestes to update the website after all
those git pushes.
- Check that the unpublished website on thyestes looks sensible.
- Run webupdate, so that all the changes on thyestes propagate to
chiark. Important to do this _before_ announcing that the release
is available.
- After running webupdate, run update-rsync on chiark and verify that
the rsync mirror package (~/ftp/putty-website-mirror) contains a
subdirectory for the new version and that the links from its
latest.html point into that subdirectory.
- Announce the release!
+ Construct a release announcement email whose message body is the
announcement written above, and which includes the following
headers:
* Reply-To:
* Subject: PuTTY X.YZ is released
+ Mail that release announcement to
.
+ Post it to comp.security.ssh.
+ Mention it in on mono.
- Edit the master ~/adm/puttysnap.sh to disable pre-release builds,
if they were previously enabled.
- Relax (slightly).

and Unix Telnet and SSH client.
If you want to rebuild PuTTY from source, we provide a variety of
Makefiles and equivalents. (If you have fetched the source from
Git, you'll have to generate the Makefiles yourself -- see
below.)
There are various compile-time directives that you can use to
disable or modify certain features; it may be necessary to do this
in some environments. They are documented in `Recipe', and in
comments in many of the generated Makefiles.
For building on Windows:
- windows/Makefile.vc is for command-line builds on MS Visual C++
systems. Change into the `windows' subdirectory and type `nmake
-f Makefile.vc' to build all the PuTTY binaries.
As of 2017, we successfully compile PuTTY with both Visual Studio
7 (2003) and Visual Studio 14 (2015), so our guess is that it will
probably build with versions in between those as well.
(The binaries from Visual Studio 14 are only compatible with
Windows XP and up. Binaries from Visual Studio 7 ought to work
with anything from Windows 95 onward.)
- Inside the windows/MSVC subdirectory are MS Visual Studio project
files for doing GUI-based builds of the various PuTTY utilities.
These have been tested on Visual Studio 7 and 10.
You should be able to build each PuTTY utility by loading the
corresponding .dsp file in Visual Studio. For example,
MSVC/putty/putty.dsp builds PuTTY itself, MSVC/plink/plink.dsp
builds Plink, and so on.
- windows/Makefile.mgw is for MinGW / Cygwin installations. Type
`make -f Makefile.mgw' while in the `windows' subdirectory to
build all the PuTTY binaries.
MinGW and friends can lag behind other toolchains in their support
for the Windows API. Compile-time levers are provided to exclude
some features; the defaults are set appropriately for the
'mingw-w64' cross-compiler provided with Ubuntu 14.04. If you are
using an older toolchain, you may need to exclude more features;
alternatively, you may find that upgrading to a recent version of
the 'w32api' package helps.
- windows/Makefile.lcc is for lcc-win32. Type `make -f
Makefile.lcc' while in the `windows' subdirectory. (You will
probably need to specify COMPAT=-DNO_MULTIMON.)
- Inside the windows/DEVCPP subdirectory are Dev-C++ project
files for doing GUI-based builds of the various PuTTY utilities.
The PuTTY team actively use Makefile.vc (with VC7/10) and Makefile.mgw
(with mingw32), so we'll probably notice problems with those
toolchains fairly quickly. Please report any problems with the other
toolchains mentioned above.
For building on Unix:
- unix/configure is for Unix and GTK. If you don't have GTK, you
should still be able to build the command-line utilities (PSCP,
PSFTP, Plink, PuTTYgen) using this script. To use it, change into
the `unix' subdirectory, run `./configure' and then `make'. Or you
can do the same in the top-level directory (we provide a little
wrapper that invokes configure one level down), which is more like
a normal Unix source archive but doesn't do so well at keeping the
per-platform stuff in each platform's subdirectory; it's up to you.
- unix/Makefile.gtk and unix/Makefile.ux are for non-autoconfigured
builds. These makefiles expect you to change into the `unix'
subdirectory, then run `make -f Makefile.gtk' or `make -f
Makefile.ux' respectively. Makefile.gtk builds all the programs but
relies on Gtk, whereas Makefile.ux builds only the command-line
utilities and has no Gtk dependence.
- For the graphical utilities, any of Gtk+-1.2, Gtk+-2.0, and Gtk+-3.0
should be supported. If you have more than one installed, you can
manually specify which one you want by giving the option
'--with-gtk=N' to the configure script where N is 1, 2, or 3.
(The default is the newest available, of course.) In the absence
of any Gtk version, the configure script will automatically
construct a Makefile which builds only the command-line utilities;
you can manually create this condition by giving configure the
option '--without-gtk'.
- pterm would like to be setuid or setgid, as appropriate, to permit
it to write records of user logins to /var/run/utmp and
/var/log/wtmp. (Of course it will not use this privilege for
anything else, and in particular it will drop all privileges before
starting up complex subsystems like GTK.) By default the makefile
will not attempt to add privileges to the pterm executable at 'make
install' time, but you can ask it to do so by running configure
with the option '--enable-setuid=USER' or '--enable-setgid=GROUP'.
- The Unix Makefiles have an `install' target. Note that by default
it tries to install `man' pages; if you have fetched the source via
Git then you will need to have built these using Halibut
first - see below.
- It's also possible to build the Windows version of PuTTY to run
on Unix by using Winelib. To do this, change to the `windows'
directory and run `make -f Makefile.mgw CC=winegcc RC=wrc'.
All of the Makefiles are generated automatically from the file
`Recipe' by the Perl script `mkfiles.pl' (except for the Unix one,
which is generated by the `configure' script; mkfiles.pl only
generates the input to automake). Additions and corrections to Recipe,
mkfiles.pl and/or configure.ac are much more useful than additions and
corrections to the actual Makefiles, Makefile.am or Makefile.in.
The Unix `configure' script and its various requirements are generated
by the shell script `mkauto.sh', which requires GNU Autoconf, GNU
Automake, and Gtk; if you've got the source from Git rather
than using one of our source snapshots, you'll need to run this
yourself. The input file to Automake is generated by mkfiles.pl along
with all the rest of the makefiles, so you will need to run mkfiles.pl
and then mkauto.sh.
Documentation (in various formats including Windows Help and Unix
`man' pages) is built from the Halibut (`.but') files in the `doc'
subdirectory using `doc/Makefile'. If you aren't using one of our
source snapshots, you'll need to do this yourself. Halibut can be
found at .

# Extra options you can set:
#
# - COMPAT=/DAUTO_WINSOCK (Windows only)
# Causes PuTTY to assume that includes its own WinSock
# header file, so that it won't try to include .
#
# - COMPAT=/DWINSOCK_TWO (Windows only)
# Causes the PuTTY utilities to include instead of
# , except Plink which _needs_ WinSock 2 so it already
# does this.
#
# - COMPAT=/DNO_SECURITY (Windows only)
# Disables use of , which is not available with some
# development environments (such as very old versions of the
# mingw/Cygwin GNU toolchain). This has the following effects:
# - Pageant won't care about the local user ID of processes
# accessing it; a version of Pageant built with this option
# will therefore refuse to run under NT-series OSes on
# security grounds (although it will run fine on Win95-series
# OSes where there is no access control anyway).
# - SSH connection sharing is disabled.
# - There is no support for restriction of the process ACLs.
#
# - COMPAT=/DNO_MULTIMON (Windows only)
# Disables PuTTY's use of , which is not available
# with some development environments. This means that PuTTY's
# full-screen mode (configurable to work on Alt-Enter) will
# not behave usefully in a multi-monitor environment.
#
# - COMPAT=/DNO_HTMLHELP (Windows only)
# Disables PuTTY's use of , which is not available
# with some development environments.
#
# If you don't have this header, you may be able to use the copy
# supplied with HTML Help Workshop.
#
# - RCFL=/DNO_MANIFESTS (Windows only)
# Disables inclusion of XML application manifests in the PuTTY
# binaries. This may be necessary to build for 64-bit Windows;
# the manifests are only included to use the XP GUI style on
# Windows XP, and the architecture tags are a lie on 64-bit.
#
# - COMPAT=/DNO_IPV6
# Disables PuTTY's ability to make IPv6 connections, enabling
# it to compile under development environments which do not
# support IPv6 in their header files.
#
# - COMPAT=/DNO_GSSAPI
# Disables PuTTY's ability to use GSSAPI functions for
# authentication and key exchange.
#
# - COMPAT=/DSTATIC_GSSAPI
# Causes PuTTY to try to link statically against the GSSAPI
# library instead of the default of doing it at run time.
#
# - COMPAT=/DMSVC4 (Windows only)
# - RCFL=/DMSVC4
# Makes a couple of minor changes so that PuTTY compiles using
# MSVC 4. You will also need /DNO_SECURITY and /DNO_MULTIMON.
#
# - COMPAT=/DNO_SECUREZEROMEMORY (Windows only)
# Disables PuTTY's use of SecureZeroMemory(), which is missing
# from some environments' header files.
#
# - XFLAGS=/DDEBUG
# Causes PuTTY to enable internal debugging.
#
# - XFLAGS=/DMALLOC_LOG
# Causes PuTTY to emit a file called putty_mem.log, logging every
# memory allocation and free, so you can track memory leaks.
#
# - XFLAGS=/DMINEFIELD (Windows only)
# Causes PuTTY to use a custom memory allocator, similar in
# concept to Electric Fence, in place of regular malloc(). Wastes
# huge amounts of RAM, but should cause heap-corruption bugs to
# show up as GPFs at the point of failure rather than appearing
# later on as second-level damage.
#
# - XFLAGS=/DFUZZING
# Builds a version of PuTTY with some tweaks to make fuzz testing
# easier: the SSH random number generator is replaced by one that
# always returns the same thing. Note that this makes SSH
# completely insecure -- a FUZZING build should never be used to
# connect to a real server.

* differs by B from the other value we've just computed. So in

* strings, so the size field indicates how much data is to
* _follow_.)
*
* The encrypted blob, once decrypted, contains a single string
* which in turn contains the payload. (This allows padding to be
* added after that string while still making it clear where the
* real payload ends. Also it probably makes for a reasonable
* decryption check.)
*
* The payload blob, for an RSA key, contains:
* - mpint e
* - mpint d
* - mpint n (yes, the public and private stuff is intermixed)
* - mpint u (presumably inverse of p mod q)
* - mpint p (p is the smaller prime)
* - mpint q (q is the larger)
*
* For a DSA key, the payload blob contains:
* - uint32 0
* - mpint p
* - mpint g
* - mpint q
* - mpint y
* - mpint x
*
* Alternatively, if the parameters are `predefined', that
* (0,p,g,q) sequence can be replaced by a uint32 1 and a string
* containing some predefined parameter specification. *shudder*,
* but I doubt we'll encounter this in real life.
*
* The key type strings are ghastly. The RSA key I looked at had a
* type string of
*
* `if-modn{sign{rsa-pkcs1-sha1},encrypt{rsa-pkcs1v2-oaep}}'
*
* and the DSA key wasn't much better:
*
* `dl-modp{sign{dsa-nist-sha1},dh{plain}}'
*
* It isn't clear that these will always be the same. I think it
* might be wise just to look at the `if-modn{sign{rsa' and
* `dl-modp{sign{dsa' prefixes.
*
* Finally, the encryption. The cipher-type string appears to be
* either `none' or `3des-cbc'. Looks as if this is SSH-2-style
* 3des-cbc (i.e. outer cbc rather than inner). The key is created
* from the passphrase by means of yet another hashing faff:
*
* - first 16 bytes are MD5(passphrase)
* - next 16 bytes are MD5(passphrase || first 16 bytes)
* - if there were more, they'd be MD5(passphrase || first 32),
* and so on.

/*
* The Miller-Rabin primality test is an extension to the Fermat
* test. The Fermat test just checks that a^(p-1) == 1 mod p; this
* is vulnerable to Carmichael numbers. Miller-Rabin considers how
* that 1 is derived as well.
*
* Lemma: if a^2 == 1 (mod p), and p is prime, then either a == 1
* or a == -1 (mod p).
*
* Proof: p divides a^2-1, i.e. p divides (a+1)(a-1). Hence,
* since p is prime, either p divides (a+1) or p divides (a-1).
* But this is the same as saying that either a is congruent to
* -1 mod p or a is congruent to +1 mod p. []
*
* Comment: This fails when p is not prime. Consider p=mn, so
* that mn divides (a+1)(a-1). Now we could have m dividing (a+1)
* and n dividing (a-1), without the whole of mn dividing either.
* For example, consider a=10 and p=99. 99 = 9 * 11; 9 divides
* 10-1 and 11 divides 10+1, so a^2 is congruent to 1 mod p
* without a having to be congruent to either 1 or -1.
*
* So the Miller-Rabin test, as well as considering a^(p-1),
* considers a^((p-1)/2), a^((p-1)/4), and so on as far as it can
* go. In other words. we write p-1 as q * 2^k, with k as large as
* possible (i.e. q must be odd), and we consider the powers
*
* a^(q*2^0) a^(q*2^1) ... a^(q*2^(k-1)) a^(q*2^k)
* i.e. a^((n-1)/2^k) a^((n-1)/2^(k-1)) ... a^((n-1)/2) a^(n-1)
*
* If p is to be prime, the last of these must be 1. Therefore, by
* the above lemma, the one before it must be either 1 or -1. And
* _if_ it's 1, then the one before that must be either 1 or -1,
* and so on ... In other words, we expect to see a trailing chain
* of 1s preceded by a -1. (If we're unlucky, our trailing chain of
* 1s will be as long as the list so we'll never get to see what
* lies before it. This doesn't count as a test failure because it
* hasn't _proved_ that p is not prime.)
*
* For example, consider a=2 and p=1729. 1729 is a Carmichael
* number: although it's not prime, it satisfies a^(p-1) == 1 mod p
* for any a coprime to it. So the Fermat test wouldn't have a
* problem with it at all, unless we happened to stumble on an a
* which had a common factor.
*
* So. 1729 - 1 equals 27 * 2^6. So we look at
*
* 2^27 mod 1729 == 645
* 2^108 mod 1729 == 1065
* 2^216 mod 1729 == 1
* 2^432 mod 1729 == 1
* 2^864 mod 1729 == 1
* 2^1728 mod 1729 == 1
*
* We do have a trailing string of 1s, so the Fermat test would
* have been happy. But this trailing string of 1s is preceded by
* 1065; whereas if 1729 were prime, we'd expect to see it preceded
* by -1 (i.e. 1728.). Guards! Seize this impostor.
*
* (If we were unlucky, we might have tried a=16 instead of a=2;
* now 16^27 mod 1729 == 1, so we would have seen a long string of
* 1s and wouldn't have seen the thing _before_ the 1s. So, just
* like the Fermat test, for a given p there may well exist values
* of a which fail to show up its compositeness. So we try several,
* just like the Fermat test. The difference is that Miller-Rabin
* is not _in general_ fooled by Carmichael numbers.)
*
* Put simply, then, the Miller-Rabin test requires us to:
*
* 1. write p-1 as q * 2^k, with q odd
* 2. compute z = (a^q) mod p.
* 3. report success if z == 1 or z == -1.
* 4. square z at most k-1 times, and report success if it becomes
* -1 at any point.
* 5. report failure otherwise.
*
* (We expect z to become -1 after at most k-1 squarings, because
* if it became -1 after k squarings then a^(p-1) would fail to be
* 1. And we don't need to investigate what happens after we see a
* -1, because we _know_ that -1 squared is 1 modulo anything at
* all, so after we've seen a -1 we can be sure of seeing nothing
* but 1s.)

##-- Makefile for cross-compiling using clang-cl, lld-link, and
## MinGW's windres for resource compilation.
#
# This makefile allows a complete Linux-based cross-compile, but
# using the real Visual Studio header files and libraries. In
# order to run it, you will need:
#
# - clang-cl, llvm-rc and lld-link on your PATH.
# * I built these from the up-to-date LLVM project trunk git
# repositories, as of 2018-05-29.
# - case-mashed copies of the Visual Studio include directories.
# * On a real VS installation, run vcvars32.bat and look at
# the resulting value of %INCLUDE%. Take a full copy of each
# of those directories, and inside the copy, for each
# include file that has an uppercase letter in its name,
# make a lowercased symlink to it. Additionally, one of the
# directories will contain files called driverspecs.h and
# specstrings.h, and those will need symlinks called
# DriverSpecs.h and SpecStrings.h.
# * Now, on Linux, define the environment variable INCLUDE to
# be a list, separated by *semicolons* (in the Windows
# style), of those directories, but before all of them you
# must also include lib/clang/5.0.0/include from the clang
# installation area (which contains in particular a
# clang-compatible stdarg.h overriding the Visual Studio
# one).
# - similarly case-mashed copies of the library directories.
# * Again, on a real VS installation, run vcvars32 or
# vcvarsx86_amd64 (as appropriate), look at %LIB%, make a
# copy of each directory, and provide symlinks within that
# directory so that all the files can be opened as
# lowercase.
# * Then set LIB to be a semicolon-separated list of those
# directories (but you'll need to change which set of
# directories depending on whether you want to do a 32-bit
# or 64-bit build).
# - for a 64-bit build, set 'Platform=x64' in the environment as
# well, or else on the make command line.
# * This is a variable understood only by this makefile - none
# of the tools we invoke will know it - but it's consistent
# with the way the VS scripts like vcvarsx86_amd64.bat set
# things up, and since the environment has to change
# _anyway_ between 32- and 64-bit builds (different set of
# paths in $LIB) it's reasonable to have the choice of
# compilation target driven by another environment variable
# set in parallel with that one.
# - for older versions of the VS libraries you may also have to
# set EXTRA_console and/or EXTRA_windows to the name of an
# object file manually extracted from one of those libraries.
# * This is because old VS seems to manage its startup code by
# having libcmt.lib contain lots of *crt0.obj objects, one
# for each possible user entry point (main, WinMain and the
# wide-char versions of both), of which the linker arranges
# to include the right one by special-case code. But lld
# only seems to mimic half of that code - it does include
# the right crt0 object, but it doesn't also deliberately
# _avoid_ including the _wrong_ ones, and since all those
# objects define a common set of global symbols for other
# parts of the library to use, lld may well select an
# arbitrary one of them the first time it sees a reference
# to one of those global symbols, and then later also select
# the _right_ one for the application's entry point, causing
# a multiple-definitions crash.
# * So the workaround is to explicitly include the right
# *crt0.obj file on the linker command line before lld even
# begins searching libraries. Hence, for a console
# application, you might extract crt0.obj from the library
# in question and set EXTRA_console=crt0.obj, and for a GUI
# application, do the same with wincrt0.obj. Then this
# makefile will include the right one of those objects
# alongside the matching /subsystem linker option.
# - also for older versions of the VS libraries, you may also
# have to set EXTRA_libs to include extra library files.

* allocate space for (a0+a1) and (b0+b1) (each just over half the
* input length n) and their product (the sum of those sizes, i.e.
* just over n itself). Then in order to actually compute the
* product, we do a recursive multiplication of size just over n.
*
* If all those 'just over' weren't there, and everything was
* _exactly_ half the length, you'd get the amount of space for a
* size-n multiply defined by the recurrence M(n) = 2n + M(n/2),
* which is satisfied by M(n) = 4n. But instead it's (2n plus a
* word or two) and M(n/2 plus a word or two). On the assumption
* that there's still some constant k such that M(n) <= kn, this
* gives us kn = 2n + w + k(n/2 + w), where w is a small constant
* (one or two words). That simplifies to kn/2 = 2n + (k+1)w, and
* since we don't even _start_ needing scratch space until n is at
* least 50, we can bound 2n + (k+1)w above by 3n, giving k=6.

* Given two input integers a,b which are not both even, computes d =
* gcd(a,b) and also two integers A,B such that A*a - B*b = d. A,B
* will be the minimal non-negative pair satisfying that criterion,
* which is equivalent to saying that 0 <= A < b/d and 0 <= B < a/d.
*
* This algorithm is an adapted form of Stein's algorithm, which
* computes gcd(a,b) using only addition and bit shifts (i.e. without
* needing general division), using the following rules:
*
* - if both of a,b are even, divide off a common factor of 2
* - if one of a,b (WLOG a) is even, then gcd(a,b) = gcd(a/2,b), so
* just divide a by 2
* - if both of a,b are odd, then WLOG a>b, and gcd(a,b) =
* gcd(b,(a-b)/2).
*
* Sometimes this function is used for modular inversion, in which
* case we already know we expect the two inputs to be coprime, so to
* save time the 'both even' initial case is assumed not to arise (or
* to have been handled already by the caller). So this function just
* performs a sequence of reductions in the following form:
*
* - if a,b are both odd, sort them so that a > b, and replace a with
* b-a; otherwise sort them so that a is the even one
* - either way, now a is even and b is odd, so divide a by 2.
*
* The big change to Stein's algorithm is that we need the Bezout
* coefficients as output, not just the gcd. So we need to know how to
* generate those in each case, based on the coefficients from the
* reduced pair of numbers:
*
* - If a is even, and u,v are such that u*(a/2) + v*b = d:
* + if u is also even, then this is just (u/2)*a + v*b = d
* + otherwise, (u+b)*(a/2) + (v-a/2)*b is also equal to d, and
* since u and b are both odd, (u+b)/2 is an integer, so we have
* ((u+b)/2)*a + (v-a/2)*b = d.
*
* - If a,b are both odd, and u,v are such that u*b + v*(a-b) = d,
* then v*a + (u-v)*b = d.
*
* In the case where we passed from (a,b) to (b,(a-b)/2), we regard it
* as having first subtracted b from a and then halved a, so both of
* these transformations must be done in sequence.
*
* The code below transforms this from a recursive to an iterative
* algorithm. We first reduce a,b to 0,1, recording at each stage
* whether we did the initial subtraction, and whether we had to swap
* the two values; then we iterate backwards over that record of what
* we did, applying the above rules for building up the Bezout
* coefficients as we go. Of course, all the case analysis is done by
* the usual bit-twiddling conditionalisation to avoid data-dependent
* control flow.
*
* Also, since these mp_ints are generally treated as unsigned, we
* store the coefficients by absolute value, with the semantics that
* they always have opposite sign, and in the unwinding loop we keep a
* bit indicating whether Aa-Bb is currently expected to be +d or -d,
* so that we can do one final conditional adjustment if it's -d.
*
* Once the reduction rules have managed to reduce the input numbers
* to (0,d), then they are stable (the next reduction will always
* divide the even one by 2, which maps 0 to 0). So it doesn't matter
* if we do more steps of the algorithm than necessary; hence, for
* constant time, we just need to find the maximum number we could
* _possibly_ require, and do that many.
*
* If a,b < 2^n, at most 2n iterations are required. Proof: consider
* the quantity Q = log_2(a) + log_2(b). Every step halves one of the
* numbers (and may also reduce one of them further by doing a
* subtraction beforehand, but in the worst case, not by much or not
* at all). So Q reduces by at least 1 per iteration, and it starts
* off with a value at most 2n.
*
* The worst case inputs (I think) are where x=2^{n-1} and y=2^n-1
* (i.e. x is a power of 2 and y is all 1s). In that situation, the
* first n-1 steps repeatedly halve x until it's 1, and then there are
* n further steps each of which subtracts 1 from y and halves it.

*
* But we have to do it in a fixed number of N-R iterations, so we
* need some error analysis to know how many we might need.
*
* The iteration is derived by defining f(r) = d - R/r.
* Differentiating gives f'(r) = R/r^2, and the Newton-Raphson

*
* r_{i+1} = r_i - f(r_i) / f'(r_i)

* that
*
* d r_i = R + e_i
* i.e. e_i/R = (r_i - r_true) / r_true
*
* so e_i is the _relative_ error in r_i.
*
* We must also introduce a rounding-error term, because the
* division by R always gives an integer. This might make the
* output off by up to 1 (in the negative direction, because
* right-shifting gives floor of the true quotient). So when we
* divide by R, we must imagine adding some f in [0,1). Then we
* have
*
* d r_{i+1} = d r_i (2 R - d r_i) / R - d f
* = (R + e_i) (R - e_i) / R - d f
* = (R^2 - e_i^2) / R - d f
* = R - (e_i^2 / R + d f)
* => e_{i+1} = - (e_i^2 / R + d f)
*
* The sum of two positive quantities is bounded above by twice
* their max, and max |f| = 1, so we can bound this as follows:
*
* |e_{i+1}| <= 2 max (e_i^2/R, d)
* |e_{i+1}/R| <= 2 max ((e_i/R)^2, d/R)
* log2 |R/e_{i+1}| <= min (2 log2 |R/e_i|, log2 |R/d|) - 1
*
* which tells us that the number of 'good' bits - i.e.
* log2(R/e_i) - very nearly doubles at every iteration (apart
* from that subtraction of 1), until it gets to the same size as
* log2(R/d). In other words, the size of R in bits has to be the
* size of denominator we're putting in, _plus_ the amount of
* precision we want to get back out.
*
* So when we multiply n (the input numerator) by our final
* reciprocal approximation r, but actually r differs from R/d by
* up to 2, then it follows that
*
* n/d - nr/R = n/d - [ n (R/d + e) ] / R
* = n/d - [ (n/d) R + n e ] / R
* = -ne/R
* => 0 <= n/d - nr/R < 2n/R
*
* so our computed quotient can differ from the true n/d by up to

* is bounded above by a constant, we can guarantee a bounded
* number of final conditional-subtraction steps.

* Modular square root, using an algorithm more or less similar to
* Tonelli-Shanks but adapted for constant time.
*
* The basic idea is to write p-1 = k 2^e, where k is odd and e > 0.
* Then the multiplicative group mod p (call it G) has a sequence of
* e+1 nested subgroups G = G_0 > G_1 > G_2 > ... > G_e, where each
* G_i is exactly half the size of G_{i-1} and consists of all the
* squares of elements in G_{i-1}. So the innermost group G_e has
* order k, which is odd, and hence within that group you can take a
* square root by raising to the power (k+1)/2.
*
* Our strategy is to iterate over these groups one by one and make
* sure the number x we're trying to take the square root of is inside
* each one, by adjusting it if it isn't.
*
* Suppose g is a primitive root of p, i.e. a generator of G_0. (We
* don't actually need to know what g _is_; we just imagine it for the
* sake of understanding.) Then G_i consists of precisely the (2^i)th
* powers of g, and hence, you can tell if a number is in G_i if
* raising it to the power k 2^{e-i} gives 1. So the conceptual
* algorithm goes: for each i, test whether x is in G_i by that
* method. If it isn't, then the previous iteration ensured it's in
* G_{i-1}, so it will be an odd power of g^{2^{i-1}}, and hence
* multiplying by any other odd power of g^{2^{i-1}} will give x' in
* G_i. And we have one of those, because our non-square z is an odd
* power of g, so z^{2^{i-1}} is an odd power of g^{2^{i-1}}.
*
* (There's a special case in the very first iteration, where we don't
* have a G_{i-1}. If it turns out that x is not even in G_1, that
* means it's not a square, so we set *success to 0. We still run the
* rest of the algorithm anyway, for the sake of constant time, but we
* don't give a hoot what it returns.)
*
* When we get to the end and have x in G_e, then we can take its
* square root by raising to (k+1)/2. But of course that's not the
* square root of the original input - it's only the square root of
* the adjusted version we produced during the algorithm. To get the
* true output answer we also have to multiply by a power of z,
* namely, z to the power of _half_ whatever we've been multiplying in
* as we go along. (The power of z we multiplied in must have been
* even, because the case in which we would have multiplied in an odd
* power of z is the i=0 case, in which we instead set the failure
* flag.)
*
* The code below is an optimised version of that basic idea, in which
* we _start_ by computing x^k so as to be able to test membership in
* G_i by only a few squarings rather than a full from-scratch modpow
* every time; we also start by computing our candidate output value
* x^{(k+1)/2}. So when the above description says 'adjust x by z^i'
* for some i, we have to adjust our running values of x^k and
* x^{(k+1)/2} by z^{ik} and z^{ik/2} respectively (the latter is safe
* because, as above, i is always even). And it turns out that we
* don't actually have to store the adjusted version of x itself at
* all - we _only_ keep those two powers of it.

/*
* PuTTY's multiprecision integer library.
*
* This library is written with the aim of avoiding leaking the input
* numbers via timing and cache side channels. This means avoiding
* making any control flow change, or deciding the address of any
* memory access, based on the value of potentially secret input data.
*
* But in a library that has to handle numbers of arbitrary size, you
* can't avoid your control flow depending on the _size_ of the input!
* So the rule is that an mp_int has a nominal size that need not be
* its mathematical size: i.e. if you call (say) mp_from_bytes_be to
* turn an array of 256 bytes into an integer, and all but the last of
* those bytes is zero, then you get an mp_int which has space for 256
* bytes of data but just happens to store the value 1. So the
* _nominal_ sizes of input data - e.g. the size in bits of some
* public-key modulus - are not considered secret, and control flow is
* allowed to do what it likes based on those sizes. But the same
* function, called with the same _nominally sized_ arguments
* containing different values, should run in the same length of time.
*
* When a function returns an 'mp_int *', it is newly allocated to an

* macros used throughout the bignum code to treat numbers as arrays
* of the most conveniently sized word for the target machine.
* Exported so that other code (e.g. poly1305) can use it too.
*
* This code must export, in whatever ifdef branch it ends up in:
*
* - two types: 'BignumInt' and 'BignumCarry'. BignumInt is an
* unsigned integer type which will be used as the base word size
* for all bignum operations. BignumCarry is an unsigned integer
* type used to hold the carry flag taken as input and output by
* the BignumADC macro (see below).
*
* - five constant macros:
* + BIGNUM_INT_BITS, the number of bits in BignumInt,
* + BIGNUM_INT_BYTES, the number of bytes that works out to
* + BIGNUM_TOP_BIT, the BignumInt value consisting of only the top bit
* + BIGNUM_INT_MASK, the BignumInt value with all bits set
* + BIGNUM_INT_BITS_BITS, log to the base 2 of BIGNUM_INT_BITS.
*
* - four statement macros: BignumADC, BignumMUL, BignumMULADD,
* BignumMULADD2. These do various kinds of multi-word arithmetic,
* and all produce two output values.
* * BignumADC(ret,retc,a,b,c) takes input BignumInt values a,b
* and a BignumCarry c, and outputs a BignumInt ret = a+b+c and
* a BignumCarry retc which is the carry off the top of that
* addition.
* * BignumMUL(rh,rl,a,b) returns the two halves of the
* double-width product a*b.
* * BignumMULADD(rh,rl,a,b,addend) returns the two halves of the
* double-width value a*b + addend.
* * BignumMULADD2(rh,rl,a,b,addend1,addend2) returns the two
* halves of the double-width value a*b + addend1 + addend2.
*
* Every branch of the main ifdef below defines the type BignumInt and
* the value BIGNUM_INT_BITS_BITS. The other constant macros are
* filled in by common code further down.
*
* Most branches also define a macro DEFINE_BIGNUMDBLINT containing a
* typedef statement which declares a type _twice_ the length of a
* BignumInt. This causes the common code further down to produce a
* default implementation of the four statement macros in terms of
* that double-width type, and also to defined BignumCarry to be
* BignumInt.
*
* However, if a particular compile target does not have a type twice
* the length of the BignumInt you want to use but it does provide
* some alternative means of doing add-with-carry and double-word
* multiply, then the ifdef branch in question can just define
* BignumCarry and the four statement macros itself, and that's fine
