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 ... WebSelect Manual.

WebApr 13, 2015 · Hash functions always produce a fixed length output regardless of the input (i.e. MD5 >> 128 bits, SHA-256 >> 256 bits), but why? I know that it is how the designer designed them to be, but why they designed the output to have the same length? So that it can be stored in a consistent fashion? easier to be compared? less complicated? … WebMay 14, 2024 · 1 Answer Sorted by: 8 SHA-256 and SHA-512 produce 256 and 512 bit hashes, respectively. 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. WebApr 22, 2024 · The SHA-2 family, of which SHA 256 is a member, was released in 2001 and includes six hash functions: SHA 224; SHA 256; SHA 384; SHA 512; SHA 512/224; SHA 512/256; Each member of the family contains a set of cryptographic hash algorithms that convert data into a unique hash value.
