title: Encryption with capital letters and without special characters
body: <p>I am searching for some encryption/decryption alghorithm which gives me only capital letters and <strong><em>without</em></strong> special characters (+,/,=). I've used <strong>DES</strong> algorithm and <strong>Rijndael (AES)</strong> algorithm, but both of those gave me special characters and mixed uppercase and lowercase characters.  </p>
  
  <p>I need readable licence to create since it will be much easier for me and for my clients to understand it when they need it. </p>
  
  <p>Please, let me know if you need more information I can give you.</p>
