This is a simple library which implements the hash functions needed by Groestlcoin. These are Groestl512, SHA1, SHA256, SHA256d, and RIPEMD160. As an ancilliary thing, it exposes hexadecimal serialization and deserialization, since these are needed to display hashes anway.
This library should always compile with any combination of features on Rust 1.41.1.
Contributions are welcome, including additional hash function implementations.
