Feasibility of creating signed PDF files
Hi, I'm looking into the feasibility of extending FOP to produce signed PDF files using the PDF Public-Key Digital Signature and Encryption Specification. What are in the issues in gluing together FOP and the JCE to produce this? Could I give the signing extension access to the entire document, to create the signature? Thanks in advance. -- http://mparaz.com/journal/ +63-916-423-7922 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
Re: Feasibility of creating signed PDF files
Hi, If I understand it properly you would need to add an Encrypt pdf object that is referenced in the documents trailer dictionary. The you would need to encrypt all pdf streams using the appropriate algorithm. If JCE can handle this then it would be used to encrypt the stream. Currently we have a few filters for other purposes, this would be another filter added to the list (I presume it needs to be last in the list) and implements PDFFilter. The encode method would do the encryption based on the algorithm and key. This filter would probably be setup using the configuration. What would need to be done: - implement the encrypt pdf object that contains the various dictionary values - implement the PDFFilter that does the encryption, using JCE - organise the configuration for password etc. I hope that answer your quesations.

[UML]: Poseidon license key
HI All, I have installed Poseidon 1.3.1 and it is asking me for the license key when I start it. But, I couldn't find anything like that in the home directory of Poseidon. Please, help me. Ramana. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
page-break-inside=avoid
My document contains one repeatingblock of data. The data varies in length with each iteration. I need to force a page break if an iteration of the block of data can notentirely fit onthe current pagepage. From what I understand page-break-inside="avoid" is the way to go about this,unfortunately it seems this feature is not yet implemented(version-0.20.3). Does anyone know of solution to this problem? Thanks in advance. T

My project is simpler - I only have to generate a signature for the stream, not encrypt it. I haven't started coding, but there is java.security.Signature.update(byte[]) which is used to build up the signature. -- http://mparaz.com/journal/ +63-916-423-7922 - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]

But, I couldn't find anything like that in the home directory of Poseidon. Please, help me. Hi, Ramana Right off Gentleware's website, for Poseidon CE: First start of Poseidon During startup, Poseidon expects to find a key file called 'InterimPoseidonCE.key' in the installation directory 'poseidon1.3', in 'poseidon1.3/bin' (this is where the installation puts it), or in your home directory. All configuration files are put in the directory 'poseidon/CE' in your home directory. If you want to set another home directory for Poseidon's configuration, set the environment variable POSEIDONCE_HOME prior to starting Poseidon. At startup, you can register with Gentleware to receive a final key for PoseidonCE. The shipped interim key runs for 1000 days, the final key is unlimited. I just downloaded and unzipped the latest, and the interim key file is certainly present, in the bin/ directory.
