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.)
