[Bug 740506] Re: verify digital signatures
i want to make digital signature valid using evince so kindly please make a fix as every one in my office use ubuntu and it will be hard for them to validate signature without adobe. or kindly send me any ubntu software that can validate dsc like adobe we are working on a closed network only i can access a public network so many commands wont run on their systems -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to poppler in Ubuntu. https://bugs.launchpad.net/bugs/740506 Title: verify digital signatures To manage notifications about this bug go to: https://bugs.launchpad.net/evince/+bug/740506/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

[Bug 740506] Re: verify digital signatures
With the iText library written in Java, many signing operations can be done: http://itextpdf.sourceforge.net/howtosign.html It should easy to understand what is don in this library and to port the code in poppler or in another library. Note: Should the use of gnome-keyring be done? -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to poppler in Ubuntu. https://bugs.launchpad.net/bugs/740506 Title: verify digital signatures To manage notifications about this bug go to: https://bugs.launchpad.net/poppler/+bug/740506/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs

An example of such signatures can be seen on http://www.aloaha.com/cache/multiplesignatures.pdf Look at the objects along the right border of the page.

The attached patched gives very basic support by providing methods for getting the signature data (/Contents), the signature type (/SubFilter i.e. PKCS7) and the ByteRanges that the verifier needs to calculate the digest over. Then the actual signature and certificate chain verification is not specific to PDF and could be implemented by the applications using any crypto library. // Markus Kilås mar...@primekey.se Reply at: https://bugs.launchpad.net/poppler/+bug/740506/comments/3 On 2010-07-28T18:25:18+00:00 Markus Kilås wrote: Sample signed document: http://wwwpriv.primekey.se/~markus/pdfsigner/SignServer3.1.3-signed.pdf Reply at: https://bugs.launchpad.net/poppler/+bug/740506/comments/4 On 2010-07-28T22:01:38+00:00 Albert Astals Cid wrote: Why force the applications to implement it? After all they are all going to do the same, so it makes sense to have it at the poppler level too. Code related i don't see why you store contents as a GooString and the others as Objects, what's the reason? Also before doing getArray() and getName() you need to check with isArray and isName, otherwise if the file is broken we will crash.

However, I was not just sure if it is good to add a dependency to a particular crypto library. There are Gnutls, openssl and NSS and possibly other? I have not used any of them for this purpose (I am mainly a Java developer now days and normally use the Bouncy Castle API). And as Brad mentions the trusted root certificates might be fetched from some keystore integrated with the desktop. I think my initial idea was to have support in poppler to get only that is needed and then an application could implement the rest and later some of that could be refactored and moved back into poppler, but that's just and idea you know better how poppler works.
