GOST resists the attacks that have recently been discovered against commonly used hashes because it has 512 bits of internal state. It combines a simple 256 bit checksum with a simple 256 bit digest.
I cannot see any use for the checksum other than to resist this type of attack against the digest, which suggests that the Russians may have been aware of this kind of attack in 1990. --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
