libkeccak_spec_cshake3
Configure cshake hashing parameters
Usage
#include <libkeccak.h> void libkeccak_spec_cshake(struct libkeccak_spec *spec, long int x, long int d);
Link with -lkeccak.
Overview
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.
Examples
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);
