LIBKECCAK_SPEC_CSHAKE(3)   Library Functions Manual   LIBKECCAK_SPEC_CSHAKE(3)

NAME
       libkeccak_spec_cshake - Configure cSHAKE hashing parameters

SYNOPSIS
       #include <libkeccak.h>

       void libkeccak_spec_cshake(struct libkeccak_spec *spec, long int x, long int d);

       Link with -lkeccak.

DESCRIPTION
       The libkeccak_spec_cshake() function sets *spec to specify the Keccak
       parameters used for cSHAKE hashing with the semicapacity specified, in
       bits, via the x parameter, and the output size specified, in bits, via
       the d parameter.

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

ERRORS
       The libkeccak_spec_cshake() function cannot fail.

EXAMPLE
       This example configure a struct libkeccak_spec to specify the Keccak
       parameters used for cSHAKE256(, 512):

       struct libkeccak_spec spec;
       libkeccak_spec_cshake(&spec, 256, 512);
