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