Idea of using GUID is the suggested approach. GUID is something unique and best.

Hi Jyoti,

you can go for GUID.its an 128-bits is big enough and the generation algorithm is unique

its look some what like this "d4235b32-9367-4c7a-8071-06e4330435ec"

You should create encrypted key everytime...
Generate yourself a secret key for the product
Take the user's name
Concatentate the users name and the secret key and hash with (for example) SHA1
Unpack the SHA1 hash as an alphanumeric string. This is the individual user's "Product Key"
Within the program, do the same hash, and compare with the product key. If equal, OK.

Hey

I believe that you are trying to make a licence key for your application, right?

You can make use of Random class to generate product key and according to that product key, you can match your licence key. Like
// Generating 16 digit product key
private string GenerateProductKey()
{
    var pKey= "";
    while (pKey.Length<16)
    {
        pKey += new Random().Next(0,10);
    }
pKey = pKey.Substring(0,16);
    return pKey;
}
