One of the simplest ways to do that is to knock up a really quick console application. Provider for its keys, so we can use that ourselves to generate our keys. The first thing we need to do is generate a publicprivate key pair for us to use in our license generation. This simple act can be quite dissuasive when it comes to piracy after all, who would want their name visible on all the torrent websites out there Enough with the waffle, lets start using Rhino Licensing.Ĭreate your key. RhinoKeys: Sign Up: Log in: Grand Theft Auto V Rockstar Digital Download CD Key from.
One particular aspect I like with this approach is that the licensee name is clearly visible in the license. The great part about using the hash of the document as the signature is that if the user tampers with the licensesuch as changing the expiration date or the licensee namethe signature will no longer match the hash the client generates, and BAM, instant invalid license. When the client generated hash and the decrypted signature match, you can be confident the sender of the message is who you think it is. When the client receives a file with a signature, it creates a hash of the file (sans- signature) and compares that hash to the decrypted value of the signature.īaring in mind that the signature is an encrypted hash of the file, if either of the public or private keys were invalid or the file had been tampered with, then the decrypted string would not match the hash of the file. In most casesand in the case of Rhino Licensingthe signature is generated by hashing the content of the file using SHA1 (or another suitable hashing algorithm), and encrypting that hash using the private key.

Rhino 5 will produce more accurate download results if you exclude using keywords like: serial, crack, keygen, code, etc. The format of the license that Rhino Licensing generates is an XML document, plain and simple.īy default, it includes the users name, an expiration date, the type of license (trial, standard, floating, etc. Other systems that use asymmetric encryption include SSH, SSL, PGP, and among others, Git uses asymmetric encryption for its security due to it using SSH. If someone tries to use a license key theyve generated themselves, it wouldnt work unless they had our exact private key. In the case of license key generation, we store our private key on the server (and never tell anyone it), and distribute the public key with our application. You encrypt a value using the one key, and it can only be decrypted using the other key.
