I've had look at the code (in poppler/ not glib/ i'll leave that to the glib/ experts) and have some minor and some major comments.
Minor: * There's 3 use of malloc i could find, for completion i guess it's better if you use gmalloc * SigStatusStruct should be a C++ class Medium: * I'm not convinced getSigningTime should return a char *, i'd very much prefer it returning an integer and shifting the responsability to turn it into a string to upper layers, since allows for translations, etc. Major: * There's lots of repeated code (the loops searching for "Annot"+"Sig" some of these with more checks for nulls than others) and some functions that make no sense in PDFDoc like Object *getByteRange(int index); If you see in Form::Form we're already parsing "Fields" and creating FormFieldSignature for each "Sig" object. My suggestion is that you expand FormFieldSignature with your implementation. That also solves API issues like for for example getSignerName should not be in PDFDoc since you need to have called validateSignature before and then it returns the signer name for the signature of that index, so it should be part of a signature object, i.e. FormFieldSignature. Do you think it makes sense? -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to poppler in Ubuntu. https://bugs.launchpad.net/bugs/740506 Title: verify digital signatures Status in Evince: Confirmed Status in Poppler: Confirmed Status in poppler package in Ubuntu: Triaged Bug description: Binary package hint: evince This is a feature request to verify digital signatures. I'm receiving more and more digitally signed PDF's and evince already acknowledges them with: Signature Not Verified Digitally signed by <signer> Date: <time stamp> Reason: <reason> Location: <location> but it would be great if Evince would be integrated into the distro's ca-certificate infrastructure to verify these signatures.
