NAME

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

SYNOPSIS

    use Crypt::OpenPGP::KeyServer;
    my $key_id = '...';
    my $server = Crypt::OpenPGP::KeyServer->new(
        Server => 'keyserver.ubuntu.com'
    );
    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( 'foo@bar.com' );

DESCRIPTION

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.

USAGE

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. There are a number of keyservers including:
```
    keyserver.ubuntu.com
    keys.openpgp.org
    
```
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.

$ring->find_keyblock_by_keyid($key_id)

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.

$ring->find_keyblock_by_uid($uid)

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.
