CTHASH (Compile Time Hash)

const fn implementation of SHA-1 SHA-2, SHA-3, Keccak, MD4, MD5 hash functions.

This crate allows you to use hash functions as constant expressions in Rust. For all other usages, the RustCrypto/hashes/ repo includes more optimized implementations of these hash functions.

Supported hash functions

• MD4 (md4)

• MD5 (md5)

• SHA-1 (sha1)

• SHA-224 (sha2_224)

• SHA-256 (sha2_256)

• SHA-384 (sha2_384)

• SHA-512 (sha2_512)

• SHA3-224 (sha3_224)

• SHA3-256 (sha3_256)

• SHA3-384 (sha3_384)

• SHA3-512 (sha3_512)

• pre-NISE Keccak-224 (keccak_256)

• pre-NISE Keccak-256 (keccak_256)

• pre-NISE Keccak-384 (keccak_384)

• pre-NISE Keccak-512 (keccak_512)

Implementation note

There is no allocation at all, no std, no unsafe, no panics, no proc macros, no nightly.
