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 refer below link https://msdn.microsoft.com/en-us/library/system.guid(v=vs.110).aspx

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 { pKey += new Random().Next(010); } pKey = pKey.Substring(016); return pKey; }

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. https://stackoverflow.com/questions/599837/how-to-generate-and-validate-a-software-license-key
