summary: Telnet command for showing TLS info


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.


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

    modules_enabled = {


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.
