WebMay 31, 2024 · The best practice for RSA encryption padding¹ is RSAES-OAEP, with a hash such as SHA-256 or SHA-512, and the MGF1 mask generation function using the same hash. The only significant change since RFC 3447 of February 2003 is the deprecation of SHA-1. RSAES-OAEP with RSA-2048 and SHA-256 is common.

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.)
