WebMar 14, 2024 · If your symmetric encryption includes Poly1305 authentication, that's great, but it requires expert care to use it safely. Don't use Poly1305 standalone unless you're an expert. 224-bit, 256-bit, 384-bit, 512-bit are all good key sizes, provided your algorithm is reasonable. Protocol-Specific Recommendations HTTPS / TLS WebJul 18, 2024 · SHA-256 claims 128-bit collision resistance, SHA-512 claims 256-bit. If or when a practical quantum computer is built, we might need the 256-bit collision resistance. Since SSL certificates typically have expiration dates in a relatively short term, it's just fine to get a SHA-256 certificate today, because it'll expire before a practical ...

Your RSA key is 1024 or 2048 bits, and the block size when using it as a cipher is the same. Since both hashes are smaller than the RSA block size, they need to be padded out to that size.
