Hi,

I have recently purchased your software and am trying to integrate it with my application. I must confess that I am ignorant when it comes to Encryption.

What I am trying to do is to generate two files one containing the LICENSE KEY and another containing the xml LICENSE PARAMETERS. I will then email these to the customers. I will write code in my application to read the license key string and License parameters string and use the EncryptedLicenseProvider.ValidateLicenseKey(string, string) to validate the license.

Is it safe to pass both the License Key and License Parameters in files to the customer instead of embedding the License Parameters in the application code?

Do you see any other problems in my approach?

Primarily I am trying to avoid having to recompile everytime I generate new License Parameters? Any alternatives?

Thanks.

If you don't embed the XML parameters in the application then a tech savvy user could simply generate their own XML parameters using the License Key Generator and then generate their own matching keys.

You could potentially workaround this by using public key encryption to sign the XML parameters file and then validate that it hasn't been tampered with. But if you don't don't know a lot about encryption it would be alot safer to simply embed the parameters in the code. The parameters generally only need to be regenerated if you change the product password (which you might do for a major new release) - not each time you issue a license.
