Alice In Cipherland

[O]nce upon a time there was a girl called Alice, and she wanted to send a message to her friend Bob. So she decided to encrypt the message so that no one can understand it. Can you find the original message, given that the encrypted message is "opptvpzfft" ?


  1. No cryptographers interested !!?

  2. Ok, one more hint,
    This encryption function contains "confusion" + "diffusion" but in their most basic forms.
