PPQ

Cryptography Library

Purpose

A simple C library implementing the SHA3 competition finalist Skein, its block cipher Threefish, and the Password Hashing Competition finalist, CATENA. Slight modifications to CATENA include: simplifying some of the ad-hoc hashing operations to produce greater-than-N-bytes of a cryptographic hash function using Skein, as Skein can output an arbitrary amount of bytes natively.

Dependencies
