It is based on the NVME polynomial as specified in the [NVM Express庐 NVM Command Set Specification](https://nvmexpress.org/wp-content/uploads/NVM-Express-NVM-Command-Set-Specification-1.0d-2023.12.28-Ratified.pdf). The code is based on the [crc64fast-nvme](https://github.com/awesomized/crc64fast-nvme.git) package in Rust and is released under the Apache 2.0 license. For more background on the exact technique used, see this [Fast CRC Computation for Generic Polynomials Using PCLMULQDQ Instruction](https://web.archive.org/web/20131224125630/https://www.intel.com/content/dam/www/public/us/en/documents/white-papers/fast-crc-computation-generic-polynomials-pclmulqdq-paper.pdf) paper. ### Performance To follow. ### Requirements All Go versions >= 1.22 are supported. ### Contributing Contributions are welcome, please send PRs for any enhancements. golang-github-minio-crc64nvme-1.1.1/crc64.go000066400000000000000000000107241504735676000204500ustar00rootroot00000000000000// Copyright (c) 2025 Minio Inc.
