cringelib

Cryptographically Secure Random Number Generator library based on the Kuznyechik block cipher algorithm. It is fast and secure. (GOST R 34.12-2015 aka RFC 7801)

Usage

Kuznyechik usage example

#include <cringelib/kuznyechik.h>

byte_t buffer[16];

kuznyechik_ctx_t kuznyechik_ctx;
kuznyechik_init_ctx(&kuznyechik_ctx);
kuznyechik_set_key(&kuznyechik_ctx, key);

kuznyechik_encrypt(&kuznyechik_ctx, buffer, plaintext);
kuznyechik_decrypt(&kuznyechik_ctx, buffer, ciphertext);

CRINGE usage example

#include <cringelib/cringe.h>

byte_t bytes[BYTES_SIZE];

cringe_t cringe;
cringe_init(&cringe);

cringe_generate_random_bytes(&cringe, bytes, BYTES_SIZE);

cringetool

Usage: -b <bytes> [-f <filename>] [-h] [-d <delimiter>]
