NAME

       pdfresurrect - tool for extracting/scrubbing versioning data from PDF documents

SYNOPSIS

       pdfresurrect  file.pdf [-w][-q][-s][-i]

DESCRIPTION

       This manual page documents briefly the pdfresurrect command.

       pdfresurrect is a tool for extracting/scrubbing versioning data from PDF documents.

OPTIONS

       A summary of options is included below.

       -w     Write the PDF versions and summary to disk.

       -q     Display only the number of versions contained in the PDF.

       -s     Scrub the previous history data from the specified PDF.

       -i     Display the creator information from the specified PDF.

NOTES

       The  scrubbing  feature	(-s) should not be trusted for any serious security uses.  After using this feature, please verify that it in fact
       zero'd all of the objects that were of concern (those objects that were to be zero'd).

       This tool relies on the application reading the pdfresurrect extracted versions to treat the last xref(cross-reference) table as  the  most
       recent in the document.	This should typically be the case.

       The  verbose output, which tries to deduce the PDF object type (e.g. stream, page), is not always accurate, and the object counts might not
       be 100% accurate.  However, this should not prevent the extraction of the versions.  This output is merely to provide a hint for  the  user
       as to what might be different between the documents.

       Object  counts  might  appear off in linearized PDF documents.  That is not truly the case, the reason for this is that each version of the
       PDF consists of the objects that compose the linear portion of the PDF plus all of the objects that compose the version in question.   Sup-
       pose there is a linearized PDF with 59 objects in its linear portion, and suppose the PDF has a second version that consists of 21 objects.
       The total number of objects in "version 2" would be 59 + 21 or 80 objects.

NAME

       CAM::PDF::Decrypt - PDF security helper

LICENSE

       See CAM::PDF.

SYNOPSIS

	   use CAM::PDF;
	   my $pdf = CAM::PDF->new($filename);

DESCRIPTION

       This class is used invisibly by CAM::PDF whenever it detects that a document is encrypted.  See new(), getPrefs() and setPrefs() in that
       module.

FUNCTIONS

       $pkg->new($pdf, $ownerpass, $userpass, $prompt)
	   Create and validate a new decryption object.  If this fails, it will set $CAM::PDF::errstr and return undef.

	   $prompt is a boolean that says whether the user should be prompted for a password on the command line.

       $self->decode_permissions($field)
	   Given a binary encoded permissions string from a PDF document, return the four individual boolean fields as an array:

	     print boolean
	     modify boolean
	     copy boolean
	     add boolean

       $self->encode_permissions($print, $modify, $copy, $add)
	   Given four booleans, pack them into a single field in the PDF style that decode_permissions can understand.	Returns that scalar.

       $self->set_passwords($doc, $ownerpass, $userpass)
       $self->set_passwords($doc, $ownerpass, $userpass, $permissions)
	   Change the PDF passwords to the specified values.  When the PDF is output, it will be encrypted with the new passwords.

	   PERMISSIONS is an optional scalar of the form that decode_permissions can understand.  If not specified, the existing values will be
	   retained.

	   Note: we only support writing using encryption version 1, even though we can read encryption version 2 as well.

       $self->encrypt($doc, $string)
	   Encrypt the scalar using the passwords previously specified.

       $self->decrypt($doc, $string)
	   Decrypt the scalar using the passwords previously specified.
