.SH SYNOPSIS
.PP
talkat [OPTION]\&... COMMAND [ARG]\&...
.SH DESCRIPTION
.PP
htalkat is a client and server for the talkat real-time text protocol,
with a curses interactive client.
Similar to talk(1) but running over a TLS connection.
.SH COMMANDS
.TP
h[elp] [COMMAND]
Give detailed usage information.
.TP
i[dentity] [PUBLIC_NAME]
Create/show/modify cryptographic identity (public and secret keys, and
certificates), setting public name to PUBLIC_NAME if given.
.TP
c[onnect] ( [talkat:]FP\[at]HOST | NAME[\[at]HOST] )
Connect to remote host, checking the public key agrees with the
fingerprint provided.
Waits for the connection to be \[lq]answered\[rq], then starts
the interactive curses client (or a user-configured client)
.TP
n[ame] ( [talkat:]FP\[at]HOST | NAME[\[at]HOST] ) NAME
Set short name (\[lq]petname\[rq]) for fingerprint and optional host.
This can be
used with the c[onnect] command, and will be used when referring to the
fingerprint.
If the name to set is omitted, it will be prompted for.
.TP
l[isten]
Start server process.
This will listen for connections on the configured
port (default: 5518), and notify by writing information to stdout and
executing the \[ti]/.htalkat/notify.sh script.
If the public key provided on an
incoming connection does not have a name associated, it will be assigned
an
automatic name +N where N is the next available positive integer.
.TP
a[nswer] [--list|-l] NAME
Answer incoming connection, starting the interactive curses client (or
a user-configured client), or list pending unanswered connections.
.TP
a[nswer] [--interactive-client|-i] NAME SOCKET_PATH
Directly spawn default (curses) client.
NAME is the name of remote to
display.
SOCKET_PATH is the path to a unix domain socket to interact with;
characters read from this socket are displayed as coming from remote,
and user input is written to the socket.
