// Package sha3 implements the SHA-3 fixed-output-length hash functions and
// the SHAKE variable-output-length hash functions defined by FIPS-202.
//
+// All types in this package also implement [encoding.BinaryMarshaler],
+// [encoding.BinaryAppender] and [encoding.BinaryUnmarshaler] to marshal and
+// unmarshal the internal state of the hash.
+//
// Both types of hash function use the "sponge" construction and the Keccak
// permutation. For a detailed specification see http://keccak.noekeon.org/
