About SHA-2

SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA). It consists of six hash functions with digests (hash values) that range from 224 to 512 bits: SHA-224, SHA-256, SHA-384, SHA-512, SHA-512/224, and SHA-512/256.

SHA-2 is widely used in various security applications and protocols, including TLS, SSL, PGP, SSH, and cryptocurrencies like Bitcoin. It is considered secure against all known attacks, and no significant weaknesses have been found in any of the SHA-2 functions.

Note:SHA-2 is considered secure for modern applications. However, it is recommended to migrate to SHA-3 for applications requiring the highest level of security, especially against quantum computing threats.
