.Sh DESCRIPTION
|
|
SHA-3 (Secure Hash Algorithm 3) is a family of cryptographic hash
|
|
functions standardized in NIST FIPS 202, first published in 2015.
|
|
It is based on the Keccak algorithm.

.Fn EVP_sha3_224 ,
|
|
.Fn EVP_sha3_256 ,
|
|
.Fn EVP_sha3_384 ,
|
|
and
|
|
.Fn EVP_sha3_512
|
|
implement the SHA3-224, SHA3-256, SHA3-384, and SHA3-512 algorithms
|
|
and produce 224, 256, 384 and 512 bits of output from a given input,
|
|
respectively.
|
|
.Sh RETURN VALUES
|
|
These functions return pointers to static
|
|
.Vt EVP_MD
|
|
objects implementing the hash functions.
