.Sh DESCRIPTION
The
.Nm cryb_sha224
family of functions implements the NIST SHA-224 message digest
algorithm as described in FIPS 180-4.
.Pp
The
.Fn cryb_sha224_init
function initializes the context structure pointed to by
.Va context .
It is the caller's responsibility to allocate this structure.
.Pp
The
.Fn cryb_sha224_update
function hashes the next
.Va len
bytes of data pointed to by the
.Va data
pointer into the given hash context.
.Pp
The
.Fn cryb_sha224_final
function finalizes the computation and writes the resulting message
digest to the caller-provided buffer pointed to by
.Va digest ,
which must be at least
.Dv SHA224_DIGEST_LEN
bytes long.
It is the caller's responsibility to dispose of the context structure
after calling
.Fn cryb_sha224_final .
.Pp
The
.Fn cryb_sha224_complete
function is a shortcut to calling
.Fn cryb_sha224_init ,
.Fn cryb_sha224_update
and
.Fn cryb_sha224_final
when the entire message is available up front in a single contiguous
buffer.
.Sh IMPLEMENTATION NOTES
The
.In cryb/sha224.h
header provides macros which allows these functions and the context
type to be referred to without their
.Dq Li cryb_
prefix.
