License Key Utility (Magic xpi 4.5)
The License Key utility generates a key derived from the end customer serial number. The tool can be used by the developer of the connector when creating a license feature for a customer.
When the end customer requests a production license for the connector:
-
Open the License Key utility.
-
In the License serial number (SN) field, paste the serial number (SN) of the end customer's production license.
-
Click the Generate button. In the Output field, you will find the usrkey value. The value is an encrypted value of the SN, using the connector's encryption key and random IV.
-
Open the makekey.exe tool found under the Magic xpi installation.
-
In the MakeKey tool, provide the feature name, expiration date, the customer SN and the VENDOR_STRING containing the usrkey as produced by the License Key utility.
-
Send the result license feature to the end customer and the end customer can add this feature to their license.
During runtime, the server searches for the license feature (as defined in the Connector Builder tool) with an identical SN as used by the server and valid expiration date, loads it and checks if the VENDOR_STRING contains the usrkey. If it does, the server extracts the value, decrypts it using the connectors key and compares the result to the server license serial number. If the two are identical, the server updates a validlicense flag to true; otherwise, the server updates the flag to false.
