SHA-2 is a family of cryptographic hash functions.

Details

As of 2012, SHA-2 has six defined-and-approved members, which can be classified into two sub-families.

  • SHA-2 family
    • SHA-256 sub-family
      • SHA-224 (224-bit)
      • SHA-256 (256-bit)
    • SHA-512 sub-family
      • SHA-512/224 (224-bit)
      • SHA-512/256 (256-bit)
      • SHA-384 (384-bit)
      • SHA-512 (512-bit)

The specification also defines t-bit hashes named SHA-512/t, for a wide range of values of t, but it only approves the aforementioned SHA-512/224 and SHA-512/256 for use.
