Among them are meta information (like “author” or “subject”), number of total pages, outline and encryption information.

All keys are optional. A PDF’s format and encryption method cannot be set or changed, these keys therefore have no effect and will be ignored. If any

If the database file doesn’t exist, it will be created with encryption by a key derived from passhprase with kdf_iter PBKDF2 [https://en.wikipedia.org/wiki/PBKDF2] iterations Fields This module also contains several field classes that implement additional logic like encryption and compression. There is also a ManyToManyField that makes it easy to work with simple many-to-many
