Posted

ByAdi Shlomo

The NAGIX system can process both encrypted and unencrypted PDF files.
One of the key ISO requirements is the “Content Copying for Accessibility” permission, which is set in Document Restrictions (File Properties → Security tab).

To specify Owner and User passwords, use the convention:

  • for specify both passwords:                ownerpassword|userpassword
  • for specify owner password only :      ownerpassword
  • for specify user password only :         |userpassword

Possible PDF encryption states

  • Encrypted with User Password only
  • Encrypted with Owner Password only
  • Encrypted with both User Password & Owner Password
  • Not encrypted

What NAGIX know at during process

  • The User password is known, but the Owner password is unknown
  • The Owner password is known, but the User password is unknown
  • Neither the Owner nor the User password is known
  • Owner and User password is known

If a PDF encrypted for opening with a User password and NAGIX does not know this password, NAGIX cannot do anything and will return an error.

Scenarios:

PDF encrypted with User Password only

  • User password provided
    NAGIX successfully insert tags.

It will also check whether Content Copying for Accessibility permission – if it not allowed – it will changed to allowed.

  • User password not provided

NAGIX successfully insert tags.

It will also check whether Content Copying for Accessibility permission – if it not allowed – it will changed to allowed.

  • User password incorrect
    NAGIX will return an error because it cannot open and read the PDF.

PDF encrypted with Owner Password only

  • Owner password provided
    NAGIX successfully insert tags.

It will also check whether Content Copying for Accessibility permission – if it not allowed – it will changed to allowed.

  • Owner password not provided

Attention, if Content Copying for Accessibility not allowed in the input file, PAC 24 will report an error.

  • Owner password incorrect
    NAGIX will return an error because it cannot open the PDF for modifications.
