Have a look at Sun's Java Cryptographic Extensions(JCE) API. There is a lot
of documentation around that helps you use this code. A good book is Java
Cryptography, written by Jonathon Knudsen and published by O'Reilly.

> s_buff.append( (char)( offset +

> public Crypto( String password ) {
> int offset = 3;
> password = crypto( password, offset );
> System.out.println( "Password encyrpted as "
> + password );
> password = crypto(password, -offset );
> System.out.println( "Password decrypted to " +
> password );
