    This may be a suitable place to ask about Java encryption libraries (depending on the question) but not really the best place to ask about techniques and best practice. StackOverflow and SoftwareEngineering are probably more suitable for those questions.

  • You might want to store the whole CC number just until the bank accepts the charge, and then delete all but the last four digits, in order to make your DB less of a target for hackers. Also, never store the 3 or 4-digit CVV after authorization has been accepted.
