This release comes with support for managing user access permissions.
There is a new option for the Encrypt command:
-perm none|all (default=none) disables/enables all user access permission flags.
From now on Encrypt will disable all user access permissions by default.
List user access permissions
pdfcpu perm list [-verbose] [-upw userpw] [-opw ownerpw] inFile
Add user access permissions
pdfcpu perm add [-verbose] [-perm none|all] [-upw userpw] -opw ownerpw inFile
Note: User access permissions will only take effect based on a set owner password.
