SHA-2 is an actively used hash function created in 2001. SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA). They are built using the Merkle–Damgård structure, from a one-way compression function itself built using the Davies–Meyer structure from a (classified) specialized block cipher. SHA-2 includes significant changes from its predecessor, SHA-1. Read more on Wikipedia...
