basic protecting of application

[nikolabob]

First i have to say that i'm have low exp in software development, so please have patience and understanding with me.

Ok, my first commercial C# appl is almost done, so i wounder what should i have to do to protect it? In the way someone can't copy and use it on other PC. What is main ways to protect your work? It is very universal application, so it will be interesting to steal.

Thanks, Nikola

There are two ways i know of: packing it and obfuscating it.
Packer Examples:
-Themida
-UPX
-Armadillo

There is no 100% protection. This is simply impossible. You can of course make it inconvenient to perform this reverse engineering, and that may well be enough.

You need a combination of licensing (for copy protection) and obfuscation (for hacker protection). See if CryptoLicensing-Crypto Obfuscator (http://www.ssware.com/cryptoobfuscator/obfuscator-net.htm) combo suits your needs.
