Hash Engine. REP XSHA1: F3 0F A6 C8: Compute a cryptographic hash (using the SHA-1 and SHA-256 functions, respectively). ES:rSI points to data to compute a hash for, ES:rDI points to a message digest and rCX specifies the number of bytes. rAX should be set to 0 at the start of a calculation.

The "crc.list" file indicates a checksum file containing 32-bit CRC checksums in brik format. As of 2012, best practice recommendations is to use SHA-2 or SHA-3 to generate new file integrity digests; and to accept MD5 and SHA-1 digests for backward compatibility if stronger digests are not available.
ISO/IEC 9797-3 Mechanisms using a universal hash-function [18] ISO/IEC 29192-6 Lightweight cryptography - Message authentication codes [19] ISO/IEC 9797-1 and -2 define generic models and algorithms that can be used with any block cipher or hash function, and a variety of different parameters.
Intel SHA Extensions are a set of extensions to the x86 instruction set architecture which support hardware acceleration of Secure Hash Algorithm (SHA) family. It was specified in 2013. [ 1 ] Instructions for SHA-512 was introduced in Arrow Lake and Lunar Lake in 2024.
SHA-2: A family of two similar hash functions, with different block sizes, known as SHA-256 and SHA-512. They differ in the word size; SHA-256 uses 32-bit words where SHA-512 uses 64-bit words. There are also truncated versions of each standard, known as SHA-224, SHA-384, SHA-512/224 and SHA-512/256. These were also designed by the NSA.
A checksum is a small-sized block of data derived from another block of digital data for the purpose of detecting errors that may have been introduced during its transmission or storage. By themselves, checksums are often used to verify data integrity but are not relied upon to verify data authenticity. [1]
It is commonly used to verify the integrity of files. It (or a variant) is installed by default on most Linux distributions . Typically distributed alongside sha1sum are sha224sum , sha256sum , sha384sum and sha512sum , which use a specific SHA-2 hash function and b2sum , [ 1 ] which uses the BLAKE2 cryptographic hash function.
