It's important here to distinguish between DSA/ECDSA and RSA. There's basically no advantage to using a truncated SHA-256 over straight SHA-256 with RSA. The performance is (of course) the same and there's plenty of room for a 256-bit hash in a 1024-bit RSA block (and people using 512-bit deserve what they get). So, defining truncated hashes really only makes sense for ECDSA/DSA and other algorithms with fixed input sizes.... -Ekr _______________________________________________ Hash mailing list Hash@lists.ietf.org https://www1.ietf.org/mailman/listinfo/hash
