Licensefile Setup and Usage

licensefile setup key and iv setup to use licensefile inside a python sdk you should first setup your key and iv key and iv are used inside python sdk for encryption and decryption process inside licensefile this process is only required once at the setup from licensespring licensefile default crypto import defaultcryptoprovider password = "your password" salt = "your salt" crypto = defaultcryptoprovider() key = crypto derive key(password=password,salt=salt) iv = crypto generate random iv() configuration setup after you have successfully setup your key and iv you should setup your configuration from licensespring licensefile config import configuration \#from licensespring hardware import hardwareidprovidersource \#the commented hardware id provider will become the default in the next major version of the sdk \#we advise using hardwareidprovidersource! 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, \#hardware id provider=hardwareidprovidersource) configuration attributes product (str) product short code api key (str,optional) your unique api key used for authentication with the licensing server shared key (str,optional) a shared secret key used alongside the api key for enhanced security during the license verification process file key (str) the encryption key used for securing license files on the client side file iv (str) the initialization vector for the encryption algorithm this complements the file key for encrypting and decrypting license files hardware id provider (object, optional) the provider class used for generating a unique hardware id this id helps in binding the license to specific hardware defaults to hardwareidprovider verify license signature (bool, optional) a boolean flag indicating whether the license's digital signature should be verified defaults to true for enhanced security signature verifier (object, optional) the class responsible for verifying the digital signature of licenses defaults to signatureverifier api domain (str, optional) the domain name of the api server with which the licensing operations are performed defaults to "api licensespring com" api version (str, optional) the version of the api to use for requests this allows for compatibility with different versions of the licensing api defaults to "v4" filename (str, optional) the default filename for saved license files this can be customized as needed defaults to "license" file path (str, optional) the path where license files should be saved on the client system if not specified, a default location is used grace period conf (int, optional) the number of hours to allow as a grace period for defaults to 24 hours is guard file enabled (bool) enables guard protection for offline licenses if set to true air gap public key (str, optional) air gap public key client id (str, optional) client id for oauth authorization purposes client secret (str, optional) client secret for oauth authorization purposes we advise for hardware id provider to use a newly developed python hardware (device) ids docid\ ordujmleqe 0sssxxa3bq provider on the next major version release hardwareidprovidersource will be set as default hardware id provider if both api keys and oauth are specified in configuration , sdk will use oauth for authorization licenseid represents a mechanism for license identification and activation, supporting both key based and user based activations methods from key(cls, key) class
