Crippin was designed to protect confidential files in case a Pocket PC is lost or stolen. It¡¯s been designed to be:
quick-and-easy to use
small (minimal executable size)
miserly (with respect to storage required both during and after encryption)
secure (using RSA encryption).
Most Crippin-encrypted files are less than half the size of the originals, so it can be used purely for compression too. If you only want to use it for compression, just leave all the password fields blank.
