How does eValid's license system work?
Can the license be customized to fit the our needs?
OK, happy to answer; it is not that complicated LErwin.
Every feature key, described here: http://e-valid.com/Products/Documentati ... atures.htm
A "license pack" which may consist of a number of lines.
Each line contains fields that include the customer name, the machine name or MAC address, the expiration date, and some other miscellaneous information.
During license key generate, a unique "hash code" is generated for each line in the license file.
That code is an 8-byte string that.
At product execution time, the plain text material in the license key is read by eValid and the "hash code" is generated using the same exact algorithm.
If the codes match, that feature is activated.
The generation of the has code is very quick and very reliable.
The algorithm that is used is a one-way function, that is, one that is quite infeasible to invert.
It is simple, effective, secure and flexible!
