The Mandos server announces itself as a Zeroconf service of type
2
 
"_mandos._tcp". The Mandos client sends a line of text where the first
3
 
whitespace-separated field is the protocol version, which currently is
4
 
"1".  The client and server then start a TLS protocol handshake with a
5
 
slight quirk: the Mandos server program acts as a TLS "client" while
6
 
the connecting Mandos client acts as a TLS "server".  The Mandos
7
 
client must supply an OpenPGP certificate, and the fingerprint of this
8
 
certificate is used by the Mandos server to look up (in a list read
9
 
from a file at start time) which binary blob to give the client.  No
10
 
other authentication or authorization is done by the server.
