You dont want your license keys to have hundreds of characters. To get access to all the features the user has to pay a license fee and receive a key. That key will then be entered into the application to unlock the full version. But this solution is already weak ( as the software itself has to include the secret key somewhere ), so I dont think this discovery invalidates the solution as far as it goes. Lowe 08 dic. 10 2010-12-08 14:49:58 5 Ive used Crypkey in the past. Generador De Claves De Licencia De Siemens Install Or UpdateHardware based IDs always become an issue when people need to reinstall or update hardware. The small dev cant. The only way to do everything you asked for is to require an internet access and verification with a server. The application needs to sign in to the server with the key, and then you need to store the session details, like the IP address. This will prevent the key from being used on several different machines. This is usually not very popular with the users of the application, and unless this is a very expensive and complicated application its not worth it. That way there wont be a single key that unlocks all everything you ever released. A simple disassembly of the.NET code will open your product to anyone. Virtual machines now allow someone to create an image of a licensed machine and run it on any platform they choose. If its not, just make it difficult enough for the casual hacker. And accept the fact that there will be unlicensed copies out there eventually. And its a pity, because for companies, license keys have almost the same value as real cash. Obfuscating the algorithm or hiding an encryption key within your software is really out of the question if you are serious about controlling licensing. If your product is successful, someone will make a key generator in a matter of days from release. You dont want every customer calling the technical support because they dont understand if the key contains a l or a 1. Your support department would thank you for this, and you will have lower costs in this area. Your license keys should be in fact signed documents, containing some useful data, signed with your companys private key. The product should validate the license keys with the corresponding public key. This way, even if someone has full access to your products logic, they cannot generate license keys because they dont have the private key. A license key would look like this: BASE32(CONCAT(DATA, PRIVATEKEYENCRYPTED(HASH(DATA)))). The biggest challenge here is that the classical public key algorithms have large signature sizes.
