The crypt/Util.hexToBytes method, with a line of debugging code at the end:
public static byte[] hexToBytes(String s) throws NumberFormatException {
if ((s.length() % 2) != 0) {
s="0"+s;
}
byte[] out = new byte[s.length() / 2];
byte b;
for (int i=0; i < s.length(); i++) {
char c = Character.toLowerCase(s.charAt(i));
if (!((c >= 'a' && c <= 'f') || (c >= '0' && c <='9')))
throw new NumberFormatException();
b = (byte) (c >= 'a' && c <='f' ? c - 'a' + 10 : c - '0');
if (i%2 == 0) {
out[i/2] = (byte) (b << 4);
} else {
out[(i-1)/2] = (byte) (out[(i-1)/2] | b);
}
}
for (int i = 0 ; i < s.length() / 2 ; i++) System.out.print(out[i]+" ");
return out;
}
The output to the byte array deviates halfway through:
