/* |
|
The permission array is composed of values taken from the following ones (specify the ones you want to block): |
|
- print : Print the document; |
|
- modify : Modify the contents of the document by operations other than those controlled by 'fill-forms', 'extract' and 'assemble'; |
|
- copy : Copy or otherwise extract text and graphics from the document; |
|
- 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); |
|
- fill-forms : Fill in existing interactive form fields (including signature fields), even if 'annot-forms' is not specified; |
|
- extract : Extract text and graphics (in support of accessibility to users with disabilities or for other purposes); |
|
- assemble : Assemble the document (insert, rotate, or delete pages and create bookmarks or thumbnail images), even if 'modify' is not set; |
|
- 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. |
|
- owner : (inverted logic - only for public-key) when set permits change of encryption and enables all other permissions. |
|
|
|
If you don't set any password, the document will open as usual. |
|
If you set a user password, the PDF viewer will ask for it before displaying the document. |
|
The master (owner) password, if different from the user one, can be used to get full document access. |
|
|
|
Possible encryption modes are: |
|
0 = RSA 40 bit |
|
1 = RSA 128 bit |
|
2 = AES 128 bit |
|
3 = AES 256 bit |
|
|
|
NOTES: |
|
- To create self-signed signature: openssl req -x509 -nodes -days 365000 -newkey rsa:1024 -keyout tcpdf.crt -out tcpdf.crt |
|
- To export crt to p12: openssl pkcs12 -export -in tcpdf.crt -out tcpdf.p12 |
|
- To convert pfx certificate to pem: openssl pkcs12 -in tcpdf.pfx -out tcpdf.crt -nodes |
