Keccak-256

Description

| The code in this module uses internal OpenSSL APIs. It may break with new versions of OpenSSL. It may also be broken for existing versions of OpenSSL. Portability of the code is unknown.

ONLY USE THIS CODE AFTER YOU HAVE VERIFIED THAT IT WORKS WITH OUR VERSION OF OPENSSL.

For details see the file cbits/keccak.c.

Keccak-256

This is the latest version of Keccak-256 hash function that was submitted to the SHA3 competition. It is different from the final NIST SHA3 hash.

The difference between NIST SHA3-256 and Keccak-256 is the use of a different padding character for the input message. The former uses '0x06' and the latter uses '0x01'.

This version of Keccak-256 is used by the Ethereum project.
