For sites wanting a local copy of the key ring info, as well as the data
itself, there is a file with the suffix ".sum" which contains the (BSD)
checksum of the file. This means that sites can poll for changes of the
file simply by fetching the sum file and seeing if that has changed. This
file is very small (12 bytes) in comparison with the main keyring
(several megabytes). Sites can also check that the datafile has been
transferred intact by checking the sum.
The files concerned are

Richard Brent has analysed
the main public keyring to identify those keys which are connected via a
chain of signatures to Phil Zimmermann's email@example.com key (and so to each
other). His analysis was performed on the keys available at 1st January
1997. All revoked keys and signatures made by them have been ignored.
trusted.pgp is a keyring containing all keys
which PRZ has signed, all keys which those have signed, and so on. trusted.sig is a detached PGP signature for
trusted.pgp. trusted.dat.gz is a gzipped
listing of those keys in order of distance from the firstname.lastname@example.org key.
For instance, those with distance 1 are signed by prz.acm. trusted.kv.gz is the output of pgp -kv ""
strong.pgp is a keyring containing all keys
which are reachable to and from PRZ. That is, they have signed or have
been signed by (possibly indirectly) email@example.com.
strong.sig is a detached PGP signature for strong.pgp and strong.kv.gz is the output of pgp -kv ""
