#summary Telnet command for showing TLS info

= Introduction =

This module adds two commands to the telnet console, `c2s:showtls()` and
`s2s:showtls()`.  These commands shows TLS parameters, such as ciphers and key
agreement protocols, of all c2s or s2s connections.

= Configuration =

Just add the module to the `modules_enabled` list.  There is no other configuration.

{{{
	modules_enabled = {
		...
			"telnet_tlsinfo";
	}
}}}

= Usage =

Simply type `c2s:showtls()` to show client connections or `s2s:showtls()`
for server-to-server connections.  These commands can also take a JID for
limiting output to matching users or servers.
