SHA-2 (Secure Hash Algorithm 2), of which SHA-256 is a part, is one of the most popular hashing algorithms out there. In cases where keys are not being generated, such as mining Bitcoin, a fast hash algorithm like SHA-2 often reigns supreme.

That said, in order to move forward let’s recap three of the main purposes of a hash function: SHA-2 is an algorithm, a generalized idea of how to hash data.

Each value (0-63) is the first 32 bits of the fractional parts of the cube roots of the first 64 primes (2 – 311).
