                                Byte encrypter v1.0
                                -------------------

This little tool can encrypt bytes from a file.

3 types of encryption are available :

# XOR encryption (0x50 XOR 0xFF -> 0xAF)
# ADD encrption (0x50 + 0xFF -> 0x4F)
# SUB encryption (0x50 - 0xFF -> 0x51)

how to use it
-------------

let's say you want to encrypt notepad.exe by using a XOR encryption with the 20 bytes at file offset 50 :

File to encrypt -> notepad.exe
Offset -> 50
Number of bytes to encrypt -> 20
type of encryption -> XOR encryption
Value -> 255 (0xFF)

click on "encrypt" and each byte will be replaced with (original_byte XOR 0xFF)

PS : I decided to do this after W00DY told me he was encrypting his last proggy "by hand".
