kek

This is a working production-quality implementation of Keccak (SHA-3) written in pure Erlang.

You probably want to use erlang-sha3 (alternate link), which

• defaults to a NIF written in C
• uses the Erlang implementation from this repository as a fallback

You can use the otpr/erlang-sha3 zomp package.

Files

• kek.erl - Keccak written in "maximally straightforward" Erlang
• kek_fast.erl - kek.erl with some loopy routines inlined
• rc.erl - scratch file to compute Keccak "round constants"
