LIBKECCAK_SPEC_SHA3(3)

NAME
libkeccak_spec_sha3 - Configure SHA-3 hashing parameters

SYNOPSIS
#include <libkeccak.h>
void libkeccak_spec_sha3(struct libkeccak_spec *spec, long int x);

Link with -lkeccak.

DESCRIPTION
The libkeccak_spec_sha3() function sets *spec to specify the Keccak parameters used for SHA-3 hashing with the output size specified, in bits, via the x parameter.

RETURN VALUES
The libkeccak_spec_sha3() function does not return any value.

ERRORS
The libkeccak_spec_sha3() function cannot fail.

EXAMPLE
This example configure a struct libkeccak_spec to specify the Keccak parameters used for SHA3-256:

struct libkeccak_spec spec;
libkeccak_spec_sha3(&spec, 256);
