SQL Server Requires Chilkat v11.7.0+

Get the Encryption and Permissions of a Loaded PDF

See more PDF Protection Examples

Demonstrates the getInfo operation of Protection, which reports how the loaded PDF is protected: the method and algorithm, whether a password is needed to open it, how it was opened (with the user password, the owner password, an empty password, or a certificate), and each permission. The loaded member describes the file as it is, the pending member describes the security it will be saved with, and changed says whether the two differ. getInfo is the one operation that does not need owner rights.
