Another unique feature of the handwriting encryption method with hieroglyphs, uncommon in other cryptographic methods, is the possibility to completely change the meaning of already written cipher text, if that becomes necessary. But that’s possible to apply only to relatively short and simple encrypted messages, not because it’s impossible with longer cipher text but because it is difficult. For instance you write down some data and someone demands you to reveal its meaning. Then, if you’re trained enough in the method, you will be able to make up in your mind the simplest matrix with letters and numbers only, and to show that the encrypted message means your name or whatever else, proving it on the spot. The encrypted script itself (by the way it looks) won’t reveal the complexity or simplicity of encryption.. all you need to do is to apply your newly made up matrix to a small number of data points in the cipher text, while “revealing” that all of the rest is just a noise.. and if few of the symbols won’t fit in then that could have just been an “error of encryption”. That’s unlikely that you will need to go to such a length as to prove a different message instead of a real message, but if that’s a possibility then you can have a simple matrix ready and to encrypt into every longer cipher text a bit of non relevant information, doing it in parallel with different cryptic symbols.
