This paper studies the security of SHA-256, SHA-384 and SHA-512 against collision attacks and provides some insight into the security properties of the basic building blocks of the structure. It is concluded that neither Chabaud and Joux’s attack, nor Dobbertin-style attacks apply.

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.
