SabreTools.Hashing

This library comprises of methods and helpers to simplify the process of getting checksums and hashes from both files and streams.

Internal Implementations

All hash and checksum types here have been written to ensure compatibility across all .NET versions. Some may have been adapted to ensure this compatibility. These can be treated as reference implementations, not always optimized.

Hash / Checksum Type	Notes
Adler-32	Based on the zlib source code
CRC	All CRC values documented here except for CRC-82 due to bit-length restrictions
Fletcher	16-, 32-, and 64-bit variants
FNV	32-, and 64-bit variants; 0, 1, and 1a algorithms
Message Digest	MD2 and MD4 only
RIPEMD	128-, 160-, 256-, and 320-bit variants
Tiger	128-, 160-, and 192-bit variants; 3- and 4-pass; 0x01 and 0x80 (Tiger2) pad-initialized
xxHash	xxHash-32 and xxHash-64 only

External Implementations

External implementations of hash and checksum types may not be compatible with all .NET versions. Please see the table below for more information about support.

Source	Hash / Checksum Types	Notes
Aaru.Checksums	SpamSum	Some code tweaks made to support older .NET versions
Blake3.NET	BLAKE3	Used in net7.0 and above
System.IO.Hashing	XXH3, XXH128	Used in net462 and above
System.Security.Cryptography	MD5, SHA-1, SHA-256, SHA-384, SHA-512, SHA3-256, SHA3-384, SHA3-512, SHAKE128, SHAKE256	Built-in library; SHA3-256, SHA3-384, SHA3-512, SHAKE128, and SHAKE256 are net8.0 and above only for supported platforms

Note: If all you care about is performance, I encourage you to forego this library and use the ones listed above directly instead.
