Witryna9 lis 2024 · SHA-1 is a 160-bit hash. SHA-2 is actually a “family” of hashes and comes in a variety of lengths, the most popular being 256-bit. The variety of SHA-2 hashes can lead to a bit of confusion, as websites and authors express them differently. If you see “SHA-2,” “SHA-256” or “SHA-256 bit,” those names are referring to the same thing. WitrynaSince SHA1 is the MUST-implement hash algorithm, if it is not explicitly in the list, it is tacitly at the end.
