Description Torsten Schlabach 2018-08-06 07:36:26 UTC
The option -dump has been introduced to pdfsig, which may be quite useful for many things; for example when trying to examine and validate signatures in scripts.

Unfortunately it's not clear what file format the dump will have. At least it would make sense to say so in the man page and usage information. It does not look like any known file format to me and also the file utility just says "data".

It is the Signature 100% verbatim as it was on the PDF file (well if the PDF is compressed, it's uncompressed)

I'm not sure what else would you want the man page to say, we can't add all the contents of the pdf spec that say how signatures are stored, etc.

Or maybe I'm wrong, adding Chinmoy in case he has a different opinion.
