sigdump patch
It would be very helpful if one of the poppler utils supported extracting
signatures from PDF files. I looked quite a bit and it seems there's no other
free pdf tool currently capable of doing this.
I'll attach a quick+dirty patch I got from Tavis Ormandy which adds a "sigdump"
tool that does this and writes a PKCS #7 object to a file. However this is just
an example, I guess a more elegant solution would be to have a parameter to the
pdfsig tool that extracts a signature to a file.</pre>
