WebApr 2, 2014 · Choice of hash function (SHA-1 vs SHA-256) does not really depend on the cipher suite, but on the protocol version. Basically, you get SHA-256 if you use TLS 1.2, SHA-1 if you use an older version. (Yes, I known this is a simplified description of a slightly more complex situation, but here it works.)

WebSHA-256 and SHA-512 are new hash functions computed with 32-bit and 64-bit words respectively. They use different numbers of shift and additive constants, but their structures are otherwise almost identical, differing only in the number of rounds. WebNov 14, 2024 · A cipher suite is a set of cryptographic algorithms.
