Re: Security on FOP
Tanks, which software? I believe that this is possible using Adobe API! but this requires adobe acrobat installed on machine!! (Acrobat reader don't install the OLE Server object) Is this true??? DS.

Lock generated PDF was Re: Security on FOP
I have a question: with FOP, Is possible to lock with a password the PDF Document generated??? No. [ snip ] You will have to do some post-processing with other software. Is this something that is not implemented? Or something that is thought to be not possible or not desirable? My understanding is that is is possible to both digitally sign and encrypt PDF files. This is described in the 'ppk_pdfspec.pdf' downloadable. Is it known that digital signing needs some form of authorit not available to authors of FOP/Apache? If so, it should surely be still possible to encrypt/lock a document. Ben.

As far as I know it's something that is beyond the capabilities of FOP and something that should stay there. My understanding is that is is possible to both digitally sign and encrypt PDF files. Using Acrobat you can do that and a lot more. However I don't think that's what Fop was designed for. You can always use Acrobat to polish a document produced with Fop. This is described in the 'ppk_pdfspec.pdf' downloadable. The fact that it is on the spec doesn't mean that it has to be implemented by Fop. Before worrying about encryption and digital signatures, Fop needs to achieve full conformance to the basic FO specification. Remember, Fop deals primarily with XSL:Fo and PDF is only one of the output methods. Is it known that digital signing needs some form of authorit not available to authors of FOP/Apache? No. If I understand it correctly you can sign your documents with any public/private key pair. Any cryptographic code may be subject to export restrictions from the US and maybe other restrictions from other countries If so, it should surely be still possible to encrypt/lock a document. Do I hear you volunteering to write the code to do it? Ben. -- Carlos E.

If it is outside the design domain for FOP, then we ought not to spend too much time on it. See below. I am actually quite keen to use a fully automated system, dispensing with the need for Acrobat, and actually locking the documnent (output from a database) against its author, as in non-repudiation. This is described in the 'ppk_pdfspec.pdf' downloadable. The fact that it is on the spec doesn't mean that it has to be implemented by Fop. Before worrying about encryption and digital signatures, Fop needs to achieve full conformance to the basic FO specification. Remember, Fop deals primarily with XSL:Fo and PDF is only one of the output methods. Fair enough, but if it is in an open spec. It is likely possible, which is what the OP was asking. I do of course agree that conformance, possibly full conformance to FO should be achieved before concentrating on minutiae such as this, which are probably only of interest to a minority. Standards conformance is in the interests of all. I think, though, that it is also true that the majority of people here have a greater interest in PDF than any other application of FOP. Furthermore there is already a high quality FO - TeX pathway, so I don't think that people would be inconvienced by an effort to 'polish' the PDF arm of this project. If so, it should surely be still possible to encrypt/lock a document. Do I hear you volunteering to write the code to do it? Yes. I am not sure that I will get started full before the end of February, but I intend to contribute to 1. Java 1.1.8 version 2. keep-with 3. Encryption All of those are things that I potentially need. Ben.
