keyd - Backend key serving daemon for the onak PGP keyserver
keyd is a backend daemon for the onak PGP keyserver. It listens on a Unix
socket for connections from the various CGI and mail front ends and
handles talking to the backend database. It is intended to be of use in
high load keyservers to reduce the time spent in connecting and
disconnecting from the key database.
keyd is currently fairly alpha code; it is only recommended that you use
it if you know what you are doing.
