While a number of key servers exist, it is only necessary to send your key to one of them. The key server will take care of the job of sending your key to all other known servers.
You can access the keyserver in e-mail, by sending mail to firstname.lastname@example.org with the command (see 8.3 below) in the Subject line of your message. This message will be sent to one of the keyservers at random, which ensures that an individual server will not be overloaded.
If you have WWW access, you can also use the WWW interface at http://www.uk.pgp.net/pgpnet/pks-commands.html.
FOUR11 no longer certifies keys. Version 1.3 of the FAQ incorrectly claimed that pobox.com certified keys, but Pobox customer service says they don't.
ADD Your PGP public key (key to add is body of msg) (-ka) INDEX List all PGP keys the server knows about (-kv) VERBOSE INDEX List all PGP keys, verbose format (-kvv) GET Get the whole public key ring (-kxa *), in multiple messages GET <userid> Get just that one key (-kxa <userid>) LAST <n> Get all keys uploaded during last <n> days
Note that instead of a user ID, you can also use a key ID. In this case, you should put "0x" in front of it. By using a key ID rather than a user ID, name or e-mail address, you ensure that you get exactly the key you want. Please see question 4.5 for more information on how to use key IDs.
If you wish to get the entire key ring and have access to FTP, it would be a lot more efficient to use FTP rather than e-mail. Download an entire keyring from ftp://ftp.pgp.net/pub/pgp/keys/README.html
