GPGstats

GPGstats calculates statistics on the keys in your key-ring.
Some of the calculated data is:

oldest key
newest key
most used key-length (in bits)
most used algorithm
domain with the most keys
tld with the most keys
what day/month/year were the most keys generated
statistics on revoked and expired keys, their average age, etc.

Download

This program also needs the GPGme library.

Download link:

gpgstats-0.5.tgz

The version working with the older versions of the GPGME library is also still available here.

Changes

0.5 migrated to new GPGME library
0.4 more new statistics
0.3 even more new statistics and it now generated nicely formatted html output
0.2 added more statistics
0.1 initial release

Example

Example output: statistics for Debian PGP keyring.

Tip

For large keyrings you might want to add

no-auto-check-trustdb

to your gpg.conf file.
