Hi everybody!
I want to generate a licence number for my program.
I want to include some informations:
a. Licence type (licencepack, oem, etc)
b. Number of licence (5-10-15-20)
c. A checksum
I can acheive this by encryptinhg a string, say LIC0001,OEM,15 -> output= 41dfaf321daaddd.
By doing a MD5, I can add the first 7 numbers of the MD5 as a checksum.
Anyway its not very advance and there are many problems related to this. Im sure there are proper ways to generate licence number.
Do y have an idea? Im waiting for your advice.
I use Delphi, mysql with standar component.
Thank you very much!
