Does anyone know if there is a custom tag that can be called from both Java
and Cold Fusion that will do encryption?
We need to encrypt credit card numbers with Cold Fusion and then decrypt
them from Java and Cold Fusion.
I have tried to write a custom tag that will do the encryption, but have
failed. I can get the custom tag to encrypt and decrypt in Cold Fusion, but
not in java even though it is calling the same class and everything. I try
to output the encrypted value in Java and after it is passed to Cold Fusion
and the results are different is different.
If I pass 1234567890123456 with the key of testing. Java says that the
encrypted form is $xx20^4Qm+SN}Bv"w'RKzt'H$CQujyw> Cold Fusion says that the
encrypted form is ]Us|2^{[Bl7NA2XAC'kt+&~H!j7jiyE7
Does anyone know why this is being converted as it is coming from java and
the custom tag to cold fusion and the output. The java code is below. (It
creates a query to return the results (could that have anything to do with
the problem???)). Thank you for your help.
