Air-Gapped Licensing

air gap licensing is a useful feature for isolated environments the concept is similar to offline license management the main difference is that in regular offline activation we exchange files and and in air gapped environments we cannot use files so we have to rely on exchanging strings in this guide you will find the instructions for implementing air gap licensing using licensespring sdk prerequisites completed the getting started docid\ lsfy9tq3vfq4roow9shkd tutorial, specifically initialized licensemanager (or licensehandler ) with your configuration using the appropriate settings activated a key based license of any type air gap configuration the air gap public key is necessary to verify the confirmation code obtained from the air gap activation portal the public key can be found on the licensespring portal under settings >keys if the air gap public key is not set correctly in the configuration, the activation process will raise an airgapactivationexception with the message "confirmation code is invalid " to set the air gap public key in the configuration use configuration setairgappublickey("your air gap public key");configuration airgappublickey = "your air gap public key";configuration airgapkey = "your air gap public key"from licensespring licensefile config import configuration conf = configuration(product="your product key",api key="your api key", shared key="your shared key",file key=key,file iv=iv, is guard file enabled=true, air gap public key="your air gap public key")licensespringconfiguration config = licensespringconfiguration builder() airgappedpublickey("\<air gap public key>") build(); to secure the air gap activation, make sure that guard file option is not set to false this feature is enabled by default and ensures that the license will not be activated multiple times with the same data, enhancing security and reliability extendedoptions enableguardfile(true);extendedoptions protectofflineactivation = true; license activation to activate a license, follow these steps open the air gap activation portal and enter the license key it will display the key and initialization code use the getairgapactivationcode method to get the activation code, passing the key and initialization code as parameters additionally, retrieve the hardware id from the sdk configuration auto activationcode = licensemanager >getairgapactivationcode( initcode, licensekey );
