The C implementation was originally based on Samuel Neves' public domain reference implementation but has since been heavily modified for the kernel. We're able to do compile-time optimizations by moving some scaffolding around the final function into the header file. Information: https://blake2.net/ Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com> Signed-off-by: Samuel Neves <sneves@dei.uc.pt> Co-developed-by: Samuel Neves <sneves@dei.uc.pt> [ardb: - move from lib/zinc to lib/crypto - remove simd handling - rewrote selftest for better coverage - use fixed digest length for blake2s_hmac() and rename to blake2s256_hmac() ] Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
