You can't encrypt an executable - it has to be unencrypted in order for the system to execute it, and any in-process code encryption would be pretty easy to break as it would have to include the decryption key in order to be any use.

Have a look at Obfuscation instead: it is about the best protection you can practically give - but it varies from company to company, and price range to price range. Google can help you: Obfuscation software[^]

thank you
I want to create a custom tool obfuscation
to protect my source code against reverse engeniring

No you don't! :laugh:
There is a huge amount of work there - unless you are going to sell it to other developers, it really isn't worth the cost of producing your own - you probably won't come up with anything as good as the existing offers, and it will take you some considerable time. You can buy an obfuscator licence for what - $150? How much of your time can you invest to match that? Half a day? Less? For some developers, $150 is the hourly rate...

yes I know but I want to create my own software obfuscation if you can help me in advance and mercuric

Sorry - no, I can't. You need a serious expert on obfuscation, and there aren't many of them around (they mostly work for companies making obfuscation software).
If you try to do it yourself, the chances are that you will do less to protect your software than you think, and more to help crackers. Look at companies like Adobe - how much per year do you think they spend on protecting photoshop? And how quickly are cracked versions of a new release available on torrent sites?
