x7 Encrypting Issue

First of all, im not asking for an importer already done or something like that.
I just would like someone to tell me wich "way" i must follow or some data about decrypting and encrypting s4 files cause i really want to learn this stuff and make it my own.
Thanks beforehand.

noone here knows it
