+.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.
+.Pp
+.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 that contain the implementations of the symmetric ciphers.
+.Sh SEE ALSO
