+.Sh DESCRIPTION
+The
+.Nm
+functions implement the cryptographic hash functions of the NIST SHA-3
+standard, FIPS PUB 202.
+The
+.Nm
+functions compress an arbitrary-length message m into short
+fixed-length octet strings SHA3-224(m), SHA3-256(m), etc., called a
+cryptographic digest or hash.
+.Pp
+Before using the
+.Nm
+functions, applications should first call
+.Xr SHA3_Selftest 3
+and confirm that it succeeded.
+.Pp
+Only the
+.Nm SHA3_256
+functions are specified in detail; the
+.Nm SHA3_224 ,
+.Nm SHA3_384 ,
+and
+.Nm SHA3_512
+functions are exactly analogous.
+.Pp
+The caller must allocate memory for a
+.Vt SHA3_256_CTX
+object to hold the state of a SHA3-256 hash computation over a
+message.
+.Vt SHA3_256_CTX
+objects are slightly over 200 bytes, and may be copied or relocated in
+memory.
+.Bl -tag -width abcd
+.It Fn SHA3_256_Init "ctx"
+Initialize a SHA3-256 context.
+Must be done before any other operations on
+.Fa ctx .
+.It Fn SHA3_256_Update "ctx" "data" "len"
+Append
+.Fa len
+octets at
+.Fa data
+to the message.
+.It Fn SHA3_256_Final "digest" "ctx"
+Store at
+.Fa digest
+the 32-octet SHA3-256 hash of the message obtained by concatenating
+all prior inputs to
+.Fn SHA3_256_Update
+on
+.Fa ctx .
+.Pp
+Subsequent use of
+.Fa ctx
+is not allowed, unless it is reinitialized with
+.Fn SHA3_256_Init .
