SHA-256
SHA-2, the name comes from the acronym for Secure Hash Algorithm 2, a cryptographic hash function algorithm standard developed by the US National Security Agency [3], by the US National Standard Released by NIST in 2001. It belongs to one of the SHA algorithms and is the successor of SHA-1. It can be further divided into six different algorithm standards, including: SHA-224, SHA-256 , SHA-384, SHA-512, SHA-512/224, SHA-512/256.
