--pdfownerpass OwnerPassword

 

The --pdfownerpass option sets the owner password to OwnerPassword. The --pdfownerpass password automatically turns on the encryption option for a PDF file.  By default, there is no owner password.

 

An encrypted PDF file has a maximum of two passwords, a user password and an owner password.  If the user or owner password is present, opening the PDF file in Adobe Acrobat requires one of these password to be entered.  The passwords can have a maximum length of 32 characters.

 

The owner password allows changes to the PDF file's password settings and other settings deemed secure.  If an owner password is present, the user must enter the owner password when prompted by the Adobe Acrobat program to allow changes to the PDF file's security settings.

 

To create an owner password that effectively makes changes to the security settings impossible, see the --pdfrandowner option.

 

Default Setting:

Owner password is not set, or does not exist if no other PDF encryption options are specified.
