LCipher2

My small KCipher2 implementation in C

Usage

After statically linking the library, initialize the cipher using init with your key and IV

#include "KCipher2.h"

unsigned int key[4] = ...; 
unsigned int iv[4] = ...;

init(key, iv);

Then, you can encrypt a buffer using kcipher2_encrypt. As KCipher2 is a stream cipher, the same function can be used for decryption.

unsigned char* text = "super secret";

kcipher2_encrypt(text, strlen(text), text); // Alternatively, output the encrypted buffer somewhere else
