SHA-2
Secure Hash Algorithm 2 family (SHA-224, SHA-256, SHA-384, SHA-512)
SHA-2 is the most widely deployed hash family today: SHA-224, SHA-256, SHA-384, SHA-512, the truncated SHA-512/224 and SHA-512/256, plus double SHA-256 as used in Bitcoin. Choose SHA-256 for general checksums and signatures, and SHA-512 when you want a longer digest or faster hashing on 64-bit CPUs. Every algorithm has a text tool and a file tool.
