https://en.wikipedia.org/wiki/PRESENT_(cipher)

Supports ECB and CBC encryption modes with 80 or 128 bit keys

Usage:

unsigned char iv[8]       = {0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01};
unsigned char key[10]     = {0x01, 0x23, 0x45, 0x67, 0x89, 0xAB, 0xCD, 0xEF, 0x01, 0x23};
unsigned char message[56] = "An 8-bit Implementation of the PRESENT block cipher in C";

present80CBC_encrypt( message, 56, key, iv );
