Xor calculation

[deepanshsinghal]

Hi everyone,

i am calculating XOR like this,

Code: Select all

   public static byte[] xor(byte[] arqc, byte[] responseCode) {

      byte[] c = new byte[arqc.length];
      for (short i = 0; i < arqc.length; i++) {
         c[i] = (byte) (arqc[i] ^ responseCode[i]);
      }

      return c;
   }

is there any other way to calculate XOR because i think it might be the reason of giving the response "6F 00"

Regards,

Please check the length of the responseCode, it's length shall greater or equal to the length of arqc!
