Christian Schlüter commented on SECURITY-563:
---------------------------------------------
even worse:
"aan2o1Y%" is encrypted an decrypted to "0?_»Ím5".
The problem is that negative BigIntegers need no leading zeroes but leading -1.
Solution:
add the following if-statement in decode-method:
for (int i = old.length - 1; i >= 0; i--)
{ encoding[i + pad] = old[i]; }
if (n.signum() == -1)
{
for (int i = 0; i < newLength - length; i++)
{ encoding[i] = (byte) -1; }
}
