preach is a Rust program using the properties of the Phi base to harden cryptography.
Cryptography is based on the fact that a payload crypted by a symmetric key give always same result.
preach allow multiple results with same payload and key, but still allowing recipient to decrypt.
preach encode each byte (0-256) on three bytes on a random choice between all forms of integer coded in Phi base.
Attacker can try brut force if he know that a payload is always starting the same, or contain always
same data at a given position.
With preach, attacker cannot know if the payload changed, or key changed, or both.
Some bytes can be encoded up to 233 different way on three bytes.
A same payload will almost never be same twice again and if it happen the symmetric key would have been changed already.
preach have to be used on payload before crypting. As size of payload becomes three time more,
compressing is recommanded after crypting in order not to help attacker with compression headers.
