or you intend to send information through the Internet. Another reason might
be to assure users cannot modify their previously entered data in a follow-up
step of a long Web transaction where you don't want to deal with server-side
session data. The goal of Crypt::Lite was to have a pretty simple way to
encrypt and decrypt data without the need to install and compile huge
packages with lots of dependencies.
Crypt::Lite generates every time a different encrypted hash when you
re-encrypt the same data with the same secret string. Nevertheless you
are able to make double or tripple-encryption with any data to increase
the security. Decryption works also on hashes that have been encrypted
on a foreign host (try this with an unpatched IDEA installation ;-).
