SSL support has been added in Relay plugin, for irc and weechat protocols.

A new option has been added to set the certificate and private key to use:

• relay.network.ssl_cert_key: path to file with certificate and private key (default: ~/.weechat/ssl/relay.pem)

The file can be created with following commands:

$ mkdir -p ~/.weechat/ssl
$ cd ~/.weechat/ssl
$ openssl req -nodes -newkey rsa:2048 -keyout relay.pem -x509 -days 365 -out relay.pem

In WeeChat :

/relay sslcertkey

And add relays with SSL, for example:

/relay add ssl.irc.freenode 8001
/relay add ssl.weechat 9001

And now WeeChat will serve clients on these ports using SSL, enjoy!
