• To load a license from a file or stream, use the class method truepy.License.load.

• To save a license to a file or stream, use the method truepy.License.store.

• To verify the siganture of a license, use the method truepy.License.verify.

• To read license information, use the truepy.License.license_data attribute; this is of the type truepy.LicenseData.

Loading and storing licenses requires only the license password; these operations do not perform signing and signature verification.
