Fausterize for Mac

Fausterize is a simple text encryption program. I wanted a encryption tool with high security and easy to remember passwords. The password is a file, a file per document, i.e. fausterize employs a one-time-pad algorithm. I was looking for an encryption tools and wondered what would happen if I change the computer / os or the company of the encryption tool would go away. I did not like the idea, but I like coding so I started fausterize. The algorithm should be simple, os and programming language independent that it could be rewritten from scratch on OS/2 and Befunge if some one wants to. On the way I tried to think of ways to break the encryption.
