Sha-2 sha-256

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.

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. See full list on github.com SHA stands for 'Secure Hash Algorithm'. It is part of the SHA-2 family, the successor to the SHA-1 algorithm, which was used from 2011 to 2015. Research into weaknesses lead to revaluation and the creation of SHA-2.

SHA-2 is an algorithm, a generalized idea of how to hash data. SHA-256 sets additional constants that define the SHA-2 algorithm’s behavior. One such constant is the output size. “256” and “512” refer to their respective output digest sizes in bits. Let’s step through an example of SHA-256.

C++ sha256 function SHA-256 is the most popular hash function in the SHA-2 family at the time of writing. It provides 128 bits of security for digital signatures and hash-only applications (SHA-1 provides only 80 bits). Remember that while MD5 and SHA-1 are both popular hash functions, MD5 is considered completely broken, SHA-1 is considered weak.

The initial spec only covered 224, 256, 384 and 512 bit variants. 2018. 8.
