Summary: NPE in AbstractCrypt
Initial Comment:
When the encryption fails, the String constructor in
wicket.util.crypt.AbstractCrypt.decrypt(AbstractCrypt.java:70)
gives a NPE.
I haven't solved the NPE with a hack, because either we
should propagate the exception in
decryptStringToByteArray, or return null. I don't know
which is better.
Cause:
wicket.util.crypt.AbstractCrypt.decryptStringToByteArray(AbstractCrypt.java:154)
: Unable to decrypt text 'bla'
javax.crypto.IllegalBlockSizeException: Input length
must be multiple of 8 when decrypting with padded cipher

:
