However, SHA-1's collision resistaSHA2The SHA-2 (Secure Hash Algorithm 2) hash functions were designed by the NSA. SHA-2 includes significant changes from its predecessor, SHA-1. The SHA-2 family consists of hash functions with digests (hash values) that are 224, 256, 384 or 51SHA3The SHA-3 (Secure Hash Algorithm 3) hash functions were released by NIST on August 5, 2015.
