Stores the permissions for an encrypted PDF.
Unencrypted PDFs implicitly have all permissions allowed.
pikepdf does not enforce the restrictions in any way. Permissions
can only be changed when a PDF is saved.

Reports encryption information for an encrypted PDF.
This information may not be changed, except when a PDF is saved.
This object is not used to specify the encryption settings to save
a PDF, due to non-overlapping information requirements.

The user password can only be retrieved when a PDF is opened
with the owner password and when older versions of the

The password is always returned as ``bytes`` even if it has

Encryptiona�
Specify the encryption settings to apply when a PDF is saved.
Args:
owner (str): The owner password to use. This allows full control
of the file. If blank, the PDF will be encrypted and
present as "(SECURED)" in PDF viewers. If the owner password
is blank, the user password should be as well.
user (str): The user password to use. With this password, some
restrictions will be imposed by a typical PDF reader.
If blank, the PDF can be opened by anyone, but only modified
as allowed by the permissions in ``allow``.
R (int): Select the security handler algorithm to use. Choose from:
``2``, ``3``, ``4`` or ``6``. By default, the highest version of
is selected (``6``). ``5`` is a deprecated algorithm that should
not be used.
allow (pikepdf.Permissions): The permissions to set.
If omitted, all permissions are granted to the user.
aes (bool): If True, request the AES algorithm. If False, use RC4.
If omitted, AES is selected whenever possible (R >= 4).
metadata (bool): If True, also encrypt the PDF metadata. If False,
metadata is not encrypted. Reading document metadata without
decryption may be desirable in some cases. Requires ``aes=True``.
If omitted, metadata is encrypted whenever possible.
