SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA). They are built using the Merkle–Damgård structure, from a one-way compression function itself built using the Davies–Meyer structure from a (classified) specialized block cipher.

Cryptographic hash functions are mathematical operations run on digital data; by comparing the computed "hash" (the output from execution of the algorithm) to a known and expected hash value, a person can determine the data's integrity. For example, computing the hash of a downloaded file and comparing the result to a previously published hash result can show whether the download has been modified or tampered with. A key aspect of cryptographic hash functions is their collision resistance: nobody should be able to find two different input values that result in the same hash output.

**SHA-2** includes significant changes from its predecessor, SHA-1.
The **SHA-2** family consists of six hash functions with digests (hash values) that are 224, 256, 384 or 512 bits:

SHA-256 and
SHA-512 are
novel hash functions computed with 32-bit and 64-bit words, respectively.
They use different shift amounts and additive constants, but their structures
are otherwise virtually identical, differing only in the number of rounds.
SHA-224 and
SHA-384 are simply truncated versions of
SHA-256 and
SHA-512 respectively,
computed with different initial values.
SHA-512/224 and
SHA-512/256 are also truncated versions of
SHA-512, but the initial values are generated
using the method described in Federal Information Processing Standards (FIPS) PUB 180-4.
**SHA-2** was published in 2001 by the National Institute of Standards and
Technology (NIST) a U.S. federal standard (FIPS). The **SHA-2** family of algorithms
are patented in US patent 6829355. The United States has released the patent under a royalty-free license.

Currently, the best public attacks break preimage resistance for 52 out of 64 rounds of SHA-256 or 57 out of 80 rounds of SHA-512, and collision resistance for 46 out of 64 rounds of SHA-256.

SHA-256 and SHA-512, and, to a lesser degree, SHA-224 and SHA-384 are prone to length extension attacks, rendering it insecure for some applications. It is thus generally recommended to switch to SHA-3 for 512-bit hashes and to use SHA-512/224 and SHA-512/256 instead of SHA-224 and SHA-256. This also happens to be faster than SHA-224 and SHA-256 on x86-64 processor architecture, since SHA-512 works on 64-bit instead of 32-bit words.
