libkeccak is C library for Keccak-family hashing, which includes SHA-3, with support for HMAC (doesn't make too much sense to use with Keccak-family functions, but it was requested). libkeccak implements a fully configurable, bit-oriented, lane-wise implementation of Keccak. libkeccak also supports marshalling and securely erasing states.
