Crypt::OpenPGP::KeyServer - Interface to HKP keyservers


    use Crypt::OpenPGP::KeyServer;

    my $key_id = '...';
    my $server = Crypt::OpenPGP::KeyServer->new(
        Server => ''
    my $kb = $server->find_keyblock_by_keyid($key_id);
    print $kb->primary_uid, "\n";
    my $cert = $kb->key;

    my @kbs = $server->find_keyblock_by_uid( '' );


Crypt::OpenPGP::KeyServer is an interface to HKP keyservers; it provides lookup by UID and by key ID. At the moment only HKP keyservers are supported; future releases will likely support the NAI LDAP servers and the email keyservers.


Crypt::OpenPGP::KeyServer->new( %arg )

Constructs a new Crypt::OpenPGP::KeyServer object and returns that object.

%arg can contain:

  • Server

    The hostname of the HKP keyserver. This is a required argument. You can get a list of keyservers through

        % host -l | grep wwwkeys
  • IncludeRevoked

    By default, revoked keys will be skipped when calling find_keyblock_by_uid. If you set IncludeRevoked to 1, find_keyblock_by_keyid will include any revoked keys in the list of keys returned.


Looks up the key ID $key_id in the keyring $ring. For consistency with the Crypt::OpenPGP::KeyRing::find_keyblock_by_keyid interface, $key_id should be either a 4-octet or 8-octet string--it should not be a string of hexadecimal digits. If you have the hex key ID, use pack to convert it to an octet string:

    pack 'H*', $hex_key_id

Returns false on failure.


Given a string $uid, searches the keyserver for all keyblocks matching the user ID $uid, including partial matches. Returns all of the matching keyblocks, the empty list on failure.
