crate has better performance than this one, with the added benefit of being
pure Rust. This library probably won't be developed any further.
blake2b_simd doesn't currently support BLAKE2s, but if there are any
callers that need it I can add support or fork the crate, so let me know.
blake2_c is a safe Rust wrapper around the C implementation of
BLAKE2. It exposes all the parameters
that BLAKE2 supports, like personalization and tree hashing.
By default this crate links against the portable "ref"
implementation, but if
you turn on the
native feature it will link against the "sse"
uses SIMD instructions if your processor supports them. That gives about an
8% speedup on my machine, but the resulting binary is probably not
This crate supports
std feature is on by default, to
provide implementations of
std::io::Write, but it can be disabled in the
default-features = false.
