WebxxHash is an extremely fast non-cryptographic hash algorithm, working at RAM speed limit. It is proposed in four flavors (XXH32, XXH64, XXH3_64bits and XXH3_128bits). The latest variant, XXH3, offers improved performance across the board, especially on small data. Benchmarks ----- The reference system uses an Intel i7-9700K cpu, and runs Ubuntu ... WebFeb 22, 2024 · Note that this assumes the size of the digest is the same, i.e. CRC64 vs an 8-byte (64-bit) truncated HMAC or CRC32 vs a 4-byte (32-bit) truncated HMAC. ... One case where this is not true and a CRC can help is if your receiver consists of a fast application CPU combined with a slow secure element, and only the secure element has the HMAC …
