The license file is also encrypted with a key derived from a password.
Quick library reference
The main class exported by truepy is truepy.License.
- To generate a new license, use the class method truepy.License.issue.
- 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.
Issuing a new license requires the private key of the issuer certificate.
Verifying a license signature requires the issuer certificate.
