Questions tagged [shacal-2]

Blockcipher based on the compression function of SHA-256. This cipher interprets the internal compression function of SHA-256 as blockcipher. The key is provided as "input data" and the input is fed into the "old state" whereas the output is the "new state". It supports keys from 128 to 512 bits, has 256-bits blocksize and 64 rounds. The best known attack breaks 49 of those rounds.

SHACAL-2 vs. AES as underlying block cipher for Secure Hash (aka SHA-256)

The hashing scheme SHA-256 (for instance) is based on Merkle-Damgård construction with the underlying compression function based on the block cipher SHACAL-2 configured in Davies Meyer mode. SHACAL-2 ...
