36 | /*
|
||
37 | The permission array is composed of values taken from the following ones (specify the ones you want to block):
|
||
38 | - print : Print the document;
|
||
39 | - modify : Modify the contents of the document by operations other than those controlled by 'fill-forms', 'extract' and 'assemble';
|
||
40 | - copy : Copy or otherwise extract text and graphics from the document;
|
||
41 | - annot-forms : Add or modify text annotations, fill in interactive form fields, and, if 'modify' is also set, create or modify interactive form fields (including signature fields);
|
||
42 | - fill-forms : Fill in existing interactive form fields (including signature fields), even if 'annot-forms' is not specified;
|
||
43 | - extract : Extract text and graphics (in support of accessibility to users with disabilities or for other purposes);
|
||
44 | - assemble : Assemble the document (insert, rotate, or delete pages and create bookmarks or thumbnail images), even if 'modify' is not set;
|
||
45 | - print-high : Print the document to a representation from which a faithful digital copy of the PDF content could be generated. When this is not set, printing is limited to a low-level representation of the appearance, possibly of degraded quality.
|
||
46 | - owner : (inverted logic - only for public-key) when set permits change of encryption and enables all other permissions.
|
||
47 | |||
48 | If you don't set any password, the document will open as usual.
|
||
49 | If you set a user password, the PDF viewer will ask for it before displaying the document.
|
||
50 | The master (owner) password, if different from the user one, can be used to get full document access.
|
||
51 | |||
52 | Possible encryption modes are:
|
||
53 | 0 = RSA 40 bit
|
||
54 | 1 = RSA 128 bit
|
||
55 | 2 = AES 128 bit
|
||
56 | 3 = AES 256 bit
|
||
57 | |||
58 | NOTES:
|
||
59 | - To create self-signed signature: openssl req -x509 -nodes -days 365000 -newkey rsa:1024 -keyout tcpdf.crt -out tcpdf.crt
|
||
60 | - To export crt to p12: openssl pkcs12 -export -in tcpdf.crt -out tcpdf.p12
|
||
61 | - To convert pfx certificate to pem: openssl pkcs12 -in tcpdf.pfx -out tcpdf.crt -nodes
