kxd - Key exchange daemon
kxd [--key=<file>] [--cert=<file>] [--data_dir=<directory>] [--email_from=<email-address>]

kxd is a key exchange daemon, which serves blobs of data (keys) over https.
It can be used to get keys remotely instead of using local storage. The main use case is
to get keys to open dm-crypt devices automatically, without having to store them on the
The server configuration is stored in a root directory (/etc/kxd/data/ by default), and
within there, with per-key directories (e.g. /etc/kxd/data/host1/key1/), each containing
the following files:
· key: Contains the key to give to the client.
· allowed_clients: Contains one or more PEM-encoded client certificates that will be
allowed to request the key. If not present, then no clients will be allowed to
access this key.
· allowed_hosts: Contains one or more host names (one per line). If not present, then
all hosts will be allowed to access that key (as long as they are authorized with a
valid client certificate).
· email_to: Contains one or more email destinations to notify (one per line). If not
present, then no notifications will be sent upon key accesses.
