LIBKECCAK_SPEC_SHA3(3)     Library Functions Manual     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);
