Encription is simple, or you can use a multiple matrix to make 128bit encription. (I think that is how it is done) I know useing a matrix is realy good to encript a message, because we did that in our math class.
For matrix, you need to learn alot about algebra!
For simple, just reverse the alphabet a=z b=y c=x...........

another way, this is a method i used for a password program - take the text you want to encrypt as an array. Cast each member to an int. Then add the present value to te last value and the next value, tis way it will be different for every string entered.
