This is the reference source code package of BLAKE2, which includes

• ref/: C implementations of BLAKE2b, BLAKE2bp, BLAKE2s, BLAKE2sp, aimed at portability and simplicity.

• sse/: C implementations of BLAKE2b, BLAKE2bp, BLAKE2s, BLAKE2sp, optimized for speed on CPUs supporting SSE2, SSSE3, SSE4.1, AVX, or XOP.

• neon/: Implementations of BLAKE2{s,b} using the NEON/ASIMD ARM instruction set.

• power8/: Implementations of BLAKE2{s,b} for POWER8, using the VSX and Altivec extensions.

• csharp/: C# implementation of BLAKE2b.

• b2sum/: Command line utility to hash files, based on the sse/ implementations.
