Hi
I would like to have some input on creating license codes. I do not really
wish to use any standard methods (like -lic files). What I need to do is the
following.
Our application will store information about the license in the user
database. I am not really afraid that the customers will try to crack the
licenses, but some level of security is needed. If the software is licensed,
the customer can install the software on multiple machines without further
licensing procedures (application checks license in the database)
The license holder will have a name and the license will expire at a certain
date. By using these two variables I want to create a license key that is
relatively easy to tell over the phone, for example xxxx-xxxx-xxxx.
The license code needs to hold information about the expiration date, but
not the customer name. However, the user has to type his customer name on
the screen and this name must be checked against the license code somehow.
If the license is correct, I store the expiration date in the database.
Any ideas? I have been trying 4 or 5 commercial products, but none really
fits my needs. I guess that this could be achieved rather easily by not to
many lines of code.
Thanks for your input!
