tiny-keccak

Benchmarks in the README show it competes with rust-crypto, achieving 238 MB/s for SHA3-256 on 4096-byte inputs, thanks to a fully unrolled Keccak permutation.

Users can compile only needed functions via Cargo.toml features like 'sha3' or 'k12', reducing binary size and dependencies, as demonstrated in the usage example.

Implements NIST standards FIPS-202 and SP800-185, providing SHA-3, SHAKE, cSHAKE, KMAC, ParallelHash, and TupleHash for reliable cryptographic operations.

Offers the fast, parallelizable KangarooTwelve algorithm as a modern alternative, catering to applications needing efficient hashing beyond traditional SHA-3.
