Can one encrypt a DLL with custom encryption?

[Nickolas]

I wasn't sure if I should post this in Security or Programming but I guess that is closer to Security. Anyway, is there a specific standard for .dll files or is there a way to apply my own encryption algorithm?

DLLs are not encrypted, so there's no "standard". You can use what you wish. Just keep in mind that when you want to execute them, you'll obviously have to decrypt them. Windows will not decrypt DLLs for you, and you cannot run encrypted DLLs for obvious reasons.

If you're searching for a "security" feature, then this is not one. First, you'll have to include key and algorithm for decryption (from which the encryption algorithm can be also deduced, btw) on on your application, and also anyone can retrieve the unencrypted DLL from RAM.

OK, so to decrypt, I have to create another program, or use the program that uses the DLL for the decryption proccess. Thanks m0skit0.

That's it. You're welcome.
