title: Dictionary based SMS encryption
body: <p>I am trying to create end to end SMS encryption application, but don't want to use standard encryption algorithm.The idea is to convert the text of message to completely different meaningful text so that over the network it doesn't seem encrypted. I am assuming messages only in English language. 
  In implementation part, I have first compressed the message using huffman encoding which gives me compressed stream of bits. Now for encryption I don't have any idea. Is it possible to build a dictionary of some random text or what other way can be used for getting such encryption? Decryption at other receiving end is also required.</p>
