+=head1 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.

+=item EVP_sha3_224(),
+EVP_sha3_256(),
+EVP_sha3_384(),
+EVP_sha3_512()
+
+The SHA-3 SHA-3-224, SHA-3-256, SHA-3-384, and SHA-3-512 algorithms
+respectively. They produce 224, 256, 384 and 512 bits of output from a given
+input.
+
+=item EVP_shake128(),
+EVP_shake256()
+
+The SHAKE-128 and SHAKE-256 Extendable Output Functions (XOF) that can generate
+a variable hash length.
+
+Specifically, B<EVP_shake128> provides an overall security of 128 bits, while
+B<EVP_shake256> provides that of 256 bits.

+=head1 RETURN VALUES
+
+These functions return a B<EVP_MD> structure that contains the
+implementation of the symmetric cipher. See L<EVP_MD_meth_new(3)> for
+details of the B<EVP_MD> structure.
