Bug#908994: diffoscope: extract information from OpenPGP keys and signatures

[Paul Wise]

Package: diffoscope
Version: 101
Severity: wishlist

When comparing OpenPGP keys or signatures (binary and ASCII-armoured),
either as raw files or embedded in other formats (like .dsc files),
it would be nice to compare the internal data of those keys and sigs.

There are some different ways to output textual data from these formats:

pgpdump:

pgpdump file
pgpdump < data

gnupg:

gpg --list-packets file
gpg --list-packets < data

For keys only:

gpg --home $(mktemp -d) file

hopenpgp-tools:

hot dump < data
hot dearmor < data | hot dump

For keys only:

hot dearmor < data | hokey lint
