So as part of my computer science course, we have been instructed to build an encryption process. I have a good knowledge on different encryption methods (RSA for example), however I am having a hard time trying to create my own.

Now, before anyone says it, I know, using homebrew methods for data encryption is dangerous and should not be used. That is not the purpose of the assignment. All we need to do is create something that works.

Thanks for any replys!

The simplest is a character substitution algorithm, sometimes called the "Caesor Cypher". Anyway, read Bruce Schneier's "Applied Cryptography". Here is a link to another text (free) that Schneier has provided and recommends: http://cacr.uwaterloo.ca/hac/index.html

Thanks! Yeah I am familiar with the Ceasor cipher, I'll check out the link, cheers!
