-.TH LIBKECCAK_DIGEST 3 LIBKECCAK
-.SH NAME
-libkeccak_digest - Complete the hashing of a message with erasure
-.SH SYNOPSIS
-.nf
-#include <libkeccak.h>
-
-int libkeccak_digest(libkeccak_state_t *\fIstate\fP, const void *\fImsg\fP, size_t \fImsglen\fP,

-.fi
-.PP
-Link with
-.IR -lkeccak .
-.SH DESCRIPTION
-The
-.BR libkeccak_digest ()
-function absorbs the last part of (or all of) a message,
-and returns the hash of the entire message. The last part
-of the message is specified by the
-.I msg
-parameter, and its byte-size is specified by the
-.I msglen
-parameter. If all of the message has already be processed
-by calls to the
-.BR libkeccak_update (3)
-function or the
-.BR libkeccak_fast_update (3)
-function (with the same pointer on
-.IR state ,)
-.I msg
-and
-.I msglen
-should be set to
-.I NULL
-and 0, respectively.
-.PP
-If the message is not comprised a whole number of bytes,
-the number of bits, modulus 8, in the message should be
-specified in the
-.I bits
-parameter.
-.I msglen
-must only count the number of whole bytes, that is, the
-floor of the number of bits in the message divided by 8.
-.PP
-.I suffix
-should be a NUL-terminated string of ASCII '1':s
-and '0':s, representing the bits that should be appended to
-the message. If this string is empty,
-.I NULL
-may be used instead. This is used to select hash algorithm.
-For pure Keccak,
-.I NULL
-or \(dq\(dq is used. For the other algorithms the constants
-.B LIBKECCAK_SHA3_SUFFIX
-(for SHA-3),
-.B LIBKECCAK_RAWSHAKE_SUFFIX
-(for RawSHAKE), and
-.B LIBKECCAK_SHAKE_SUFFIX
-(for SHAKE) are used.
-.PP
-The hash of the message will be stored to
-.IR hashsum ,
-unless
-.I hashsum
-is
-.I NULL
-(which increases the performance of the call.) A total of
-.RI (( state->n
-+ 7) / 8) bytes will be written to the beginning of
-.IR hashsum .
-Therefore,
-.I hashsum
-needs at least an allocation size of that number of bytes.
-.PP
-The
-.BR libkeccak_digest ()
-function may reallocate the state's message chunk buffer.
-When doing so, it attempts to do so as securely as possible,
-rather than as fast as possible.
-.SH RETURN VALUES
-The
-.BR libkeccak_digest ()
-function returns 0 upon successful completion. On error,
--1 is returned and
-.I errno
-is set to describe the error.
-.SH ERRORS
-The
-.BR libkeccak_digest ()
-function may fail for any reason specified by the function
-.BR malloc (3).
-.SH EXAMPLE
-This example calculates the Keccak[b = 1024, c = 576, n = 256]
-hash of the input from stdin, and prints the hash, in hexadecimal
-form, to stdout.

-.SH NOTES
-Be aware,

-hashes the file until the end has been reached. For pipes
-and sockets and this means until the file has been closed.
-But for character devices, this usually means never.
-Attempting to hash files in /dev is therefore usually a
-bad idea.
-.BR libkeccak_generalised_sum_fd ()
-does not check for the file length or file type before
-hashing as this could limit what you can do, and make
-the library more complex.
-.PP
-.BR libkeccak_generalised_sum_fd ()
-does not stop if interrupted
-.RB ( read (2)
