# Non-scientific hash benchmarks

Benchmarks of various hash algorithms with Ruby.

## Algorithms

* Ruby stdlib:

  * [MD5][]

  * [SHA1][]/[SHA256][SHA2]/[SHA512][SHA2]

  * [Zlib CRC32][]

* Gems:

  * [digest-xxhash][] (XXH32/XXH64/XXH3)

  * [murmurhash3][] (32/128)

  * [cityhash][] (32/64/128)

  * [openssl][] (MD5, SHA1, SHA256, SHA512, SHA3)

These algorithms are not all equivalent so don't just blindly pick the fastest one!
