LIBKECCAK_SPEC_CSHAKE(3)

💖 libkeccak_spec_cshake(3) — Configure cSHAKE hashing parameters 💖

okay bestie, this page lives in the LIBKECCAK manual, and it is literally all about setting up cSHAKE hashing parameters. no cap, it’s giving “small function, very important job.” 💅

🌸 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 🦋

okay so libkeccak_spec_cshake() 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.

that’s the whole assignment, bestie. it configures the params and minds its own business. iconic. ✨

🎀 RETURN VALUES 🎀

libkeccak_spec_cshake() does not return any value.

not a single little value. void behavior fr fr. 🫶

⚠️ ERRORS ⚠️

libkeccak_spec_cshake() cannot fail.

that’s right — no error era, no fail vibe, it literally cannot. 💀

🍓 EXAMPLE 🍓

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

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