#include "AESLib.h"

void setup() {
Serial.begin(9600);
uint8_t key[] = {0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15};
char data[] = "0000000000000024"; //origanally only 16 chars
aes128_enc_single(key, data);
Serial.print("encrypted:");
for (byte i=0; i<16; i++) {
  Serial.print(data[i]&0xFF,HEX);
  Serial.print(" ");
}
Serial.println();
aes128_dec_single(key, data);
Serial.print("decrypted:");
Serial.println(data);
}

void loop() {
  // put your main code here, to run repeatedly:
}

Does asking you to tell us what error message is asking too much?

Try starting with a library example.
