NAME¶
libkeccak_spec_shake - Configure SHAKE hashing parameters
SYNOPSIS¶
#include <libkeccak.h> void libkeccak_spec_shake(struct libkeccak_spec *spec, long int x, long int d);
Link with -lkeccak.
DESCRIPTION¶
The libkeccak_spec_shake() function sets *spec to specify the Keccak parameters used for SHAKE 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_shake() function does not return any value.
ERRORS¶
The libkeccak_spec_shake() function cannot fail.
EXAMPLE¶
This example configure a struct libkeccak_spec to specify the Keccak parameters used for SHAKE256(, 512):
struct libkeccak_spec spec; libkeccak_spec_shake(&spec, 256, 512);
