I don't have a file. Bug 44085 contains a large file test case. But I
don't know how to sign it.

Implementing large file support is simply a case of using obj.isInt64()/
obj.getInt64() when getting the range offsets.

In addition, the code should avoid reading the entire range into memory
instead processing it in smaller chunks. From a quick look a the nss
headers it appears to have support for incremental hashing. This is good
practice even for < 2GB files as I have seen scanned PDFs that are in
the 100's of MB range.

I don't mind adding the getInt64() stuff myself as that is easy to do
without needing to understand the rest of the code. But the incremental
hashing would best be done by the original developer of the patch.

So at a a minimum if we can get the incremental hashing in then I can
sort out the rest of the 64-bit support.

  verify digital signatures

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.
