i can write one unique formula, but cannot decide which bit/byte-operation functions are well-known to the readers.
In fact it is sufficient to use chr(), asc() and mod(,16)

OK! You are genius! I have tried to do simple subtraction for each whole byte from key:
48 06 B3 00
but I always got some random wrong decrypted byte as say above. It had entered me to a screeching halt!!! The key was obvious after comparing of two simple and very small file that was made by GPICreator - one is encrypted and second is non-encrypted. Script for HEX editor worked fine. But always just a little broken result was on screen.
It is pity what HEX editor is not operable with this algorithm. I am a deep stupid. So hope to you or may be syzygy give a ready for use program decision...
