Creates a deactivation verification code.
string CreateDeactivationCode(string activationKey, string computerID, ELicenseBinding licenseBinding)
|activationKey||string||the activation key to be deactivated|
|computerID||string||the computerID of the computer being deactivated. This value can be empty if the LicenseBinding argument is set to a specific value.|
|licenseBinding||ELicenseBinding||the license binding value. The computerID will be calculated based on the license binding value. This parameter is not required if computerID is specified.|
|string||the deactivation verification code|
A deactivation verification code is used to confirm that a user has indeed deactivated his/her license from a computer that is offline. If you are using your own user interface for activation/deactivation, you can use this function to generate a deactivation verification code. After the user deactivates his/her license, you need to display the code to the user and ask the user to send you that code.
You can then use the Deactivation code in 3 different contexts:
- When deactivating a key from the QLM Management Console / Manage Keys / Deactivate
- When deactivating a key from the QLM Portal / Release
- When deactivating a key from the QLM Self Help. To enable the DVC in the QLM Self Help, you must set the Server Property customerSite/showDeactivationVerificationCode to true.
Note that a deactivation verification code expires in 1 day.
To create your own function to calculate the deactivation code, you need to compute the MD5 hash of the following concatenated strings
Activation Key (without dashes)|ComputerID|CommunicationEncryptionKey|Current date (yyyy-MM-dd)
