MZ-Crypt v1.0 decryptor


Recommended Posts

Hello guys...

A few days after my BJFnt decryptor, i'm proud to bring you my MZ-Crypt v1.0 decryptor. :D

There is a very important bug in the cryptor (including its original decryption engine).

It (de)crypts one byte more than the raw size of current section, so it can encrypt an uncryptable section, resulting in a crash :angry: of crypted program.

This decryptor does in the same way, in order to get original file before this one was crypted. :thumbsup:

I have also included source code in masm for those who are interested...

See you soon in my next decrypter... Perhaps decruncher/unpacker if enough time...
