Quoting the project page

   This is a fast and simple, yet hard to crack encryption program. It
   uses XOR encryption with variable key, based on the password that user
   inputs to the program

I read the code quickly -- it is a simple repeated XOR of the key
against the ciphertext, with a couple of twists that don't change the
strength at all. It could have been broken way over a century ago by
someone of modest skill. Today I'd happily assign breaking it as a
homework exercise to intro cryptography students.

At least this is an open source project instead of some commercial
