I create a triple DES key from the a byte array ("skBytes") but when calling getEncoded on the triple DES key ("sk") and comparing it to the byte array, they differ! They are almost the same if you look at the console output, though. How would I create a triple DES key that is exactly as "skBytes"?
byte[] skBytes = {(byte) 0x41, (byte) 0x0B, (byte) 0xF0, (byte) 0x9B, (byte) 0xBC, (byte) 0x0E, (byte) 0xC9, (byte) 0x4A, (byte) 0xB5, (byte) 0xCE, (byte) 0x0B, (byte) 0xEA, (byte) 0x05, (byte) 0xEF, (byte) 0x52, (byte) 0x31, (byte) 0xD7, (byte) 0xEC, (byte) 0x2E, (byte) 0x75, (byte) 0xC3, (byte) 0x1D, (byte) 0x3E, (byte) 0x61};
DESedeKeySpec keySpec = new DESedeKeySpec(skBytes);
SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DESede");
SecretKey sk = keyFactory.generateSecret(keySpec);
for(int i = 0; i < skBytes.length; i++)
{
System.out.println("(sk.getEncoded()[i], skBytes[i]) = (" + sk.getEncoded()[i] +", " + skBytes[i] + ")");
}
Console output:
(sk.getEncoded()[i], skBytes[i]) = (64, 65)
(sk.getEncoded()[i], skBytes[i]) = (11, 11)
(sk.getEncoded()[i], skBytes[i]) = (-15, -16)
