Detailed Description

Primitive.

Threefish-256 is a block cipher with a 256-bit block size and a 256-bit key size. It also has an optional 128-bit tweak, which can be set through the cipher parameters.

The Threefish ciphers were originally designed to be used as a building block for the Skein hash function family.
