Hi, i have a dll and i want to encrypt it to hide (obfuscate ??) an important algorithm used here. Well today i'm using a following approach: I'm encrypting the dll with a program, then when i want to loadlibrary() it, i decrypt it to a plain-text file, then i loadlibrary the plain-text file. So i have my encrypted dll and i have a plain-text version either. To mitigate this vulnerability, i'm using EFS to protect my plain-text dll. I'm wondering if using the PE format i can do some kind of "on-the-fly encrypt and decrypt". Is it possible ? There is any example ? Is it a good solution ? Thanks in advance, Victor
