WebTLS 1.0 and 1.1 All TLS 1.0/1.1 authenticated PFS (Perfect Forward Secrecy) ciphersuites use SHA1 alone or MD5+SHA1. That leaves only unauthenticated ones (which are vulnerable to MiTM so we discount them) or those using static keys. Theoretically that would permit RSA, DH or ECDH keys in certificates but in practice everyone uses RSA. WebJun 9, 2015 · The version used by SSLv3 would have been SHA-1, just like TLS 1.0: SHA The Secure Hash Algorithm is defined in FIPS PUB 180-1. It produces a 20-byte output.
