I just made a little gui for ciphersaber2, an arcfour-based (rc4) encryption utility for files which I compiled today. It is a little like Pcrypt but uses a different algorithm. Here is a bit from the help:
Have fun with it....Pcipher is a gui based on Pcrypt (thanks coolpup and soliver) but
uses a different encryption/decryption engine. Pcipher makes use
of ciphersaber2, which is based on arc4 (rc4, arcfour). It is pretty
secure and simple.
You will have to enter a password (remember it well) and the number
of "shuffles" that will be undertaken (say 20 or 30). Remember the
number of shuffles too, since you will not be able to decrypt your
file if you enter an invalid "shuffles" number. The gui will default
to 20, which is an acceptable value. You don't really have to change
it, unless you have particular security needs.
With kind regards,

PS. The source to ciphersaber2 is included and located in /usr/local/Pcipher/src together with minimal compilation instructions.
