Is SHA-2 and Sha 256 the same?
SHA-2 is actually a “family” of hashes and comes in a variety of lengths, the most popular being 256-bit. If you see “SHA-2,” “SHA-256” or “SHA-256 bit,” those names are referring to the same thing. If you see “SHA-224,” “SHA-384,” or “SHA-512,” those are referring to the alternate bit-lengths of SHA-2.
