## Toxygen Weechat

You can have a [weechat](https://github.com/weechat/qweechat)
console so that you can have IRC and jabber in a window as well as Tox.
There's a copy of qweechat in ```thirdparty/qweechat``` backported to
PyQt5 and integrated into toxygen. Follow the normal instructions for
adding a ```relay``` to [weechat](https://github.com/weechat/weechat)
```
/relay add ipv4.ssl.weechat 9000
/relay start ipv4.ssl.weechat
```
or
```
/set relay.network.ipv6 off
/set relay.network.password password
/relay add weechat 9000
/relay start weechat
```
and use the Plugins/Weechat Console to start weechat under Toxygen.
Then use the File/Connect menu item of the Console to connect to weechat.

Weechat has a Jabber plugin to enable XMPP:
```
/python load jabber.el
/help jabber
```
so you can have Tox, IRC and XMPP in the same application!

### Creating servers for IRC over Tor

Create a proxy called tor
```
/proxy add tor socks5 127.0.0.1 9050
```

It should now show up in the list of proxies.
```
/proxy list
```

```
/nick NickName
```

## TLS certificates

[Create a Self-signed Certificate](https://www.oftc.net/NickServ/CertFP/)

Choose a NickName you will identify as.

Create a directory for your certificates ~/.config/weechat/ssl/ 
and make a subdirectory for each server ~/.config/weechat/ssl/irc.oftc.net/ 

Change to the server directory and use openssl to make a keypair and answer the questions:
```
openssl req -nodes -newkey rsa:2048 -keyout NickName.key -x509 -days 3650 -out NickName.cer
chmod 400 NickName.key
```
We now combine certificate and key to a single file NickName.pem 
```
cat NickName.cer NickName.key > NickName.pem
chmod 400 NickName.pem
```

Do this for each server you want to connect to, or just use one for all of them.

### Libera TokTok channel

The main discussion forum for Tox is the #TokTok channel on libera.

https://mox.sh/sysadmin/secure-irc-connection-to-freenode-with-tor-and-weechat/
We have to create an account without Tor, this is a requirement to use TOR:
Connect to irc.libera.chat without Tor and register 
```
/msg NickServ identify NickName password
/msg NickServ REGISTER mypassword mycoolemail@example.com
/msg NickServ SET PRIVATE ON
```
You'll get an email with a registration code.
Confirm registration after getting the mail with the code:
```
/msg NickServ VERIFY REGISTER NickName code1235678
```

Libera has an onion server so we can map an address in tor. Add this
to your /etc/tor/torrc
```
MapAddress palladium.libera.chat libera75jm6of4wxpxt4aynol3xjmbtxgfyjpu34ss4d7r7q2v5zrpyd.onion
```
Or without the MapAddress just use
libera75jm6of4wxpxt4aynol3xjmbtxgfyjpu34ss4d7r7q2v5zrpyd.onion
as the server address below, but set tls_verify to off.

Define the server in weechat
https://www.weechat.org/files/doc/stable/weechat_user.en.html#irc_sasl_authentication
```
/server remove libera
/server add libera palladium.libera.chat/6697 -tls -tls_verify
/set irc.server.libera.ipv6 off
/set irc.server.libera.proxy tor
/set irc.server.libera.username NickName
/set irc.server.libera.password password
/set irc.server.libera.nicks NickName
/set irc.server.libera.tls on
/set irc.server.libera.tls_cert "${weechat_config_dir}/ssl/libera.chat/NickName.pem"
```

```
/set irc.server.libera.sasl_mechanism ecdsa-nist256p-challenge
/set irc.server.libera.sasl_username "NickName"
/set irc.server.libera.sasl_key "${weechat_config_dir}/ssl/libera.chat/NickName.pem"
```

Disconnect and connect back to the server. 
```
/disconnect libera
/connect libera
```

/msg nickserv identify password NickName


### oftc.net

To use oftc.net over tor, you need to authenticate by SSL certificates.


Define the server in weechat
```
/server remove irc.oftc.net
/server add OFTC irc.oftc.net/6697  -tls -tls_verify
/set irc.server.OFTC.ipv6 off
/set irc.server.OFTC.proxy tor
/set irc.server.OFTC.username NickName
/set irc.server.OFTC.nicks NickName
/set irc.server.OFTC.tls on
/set irc.server.OFTC.tls_cert "${weechat_config_dir}/ssl/irc.oftc.chat/NickName.pem"

# Disconnect and connect back to the server. 
/disconnect OFTC
/connect OFTC
``` 
You must be identified in order to validate using certs
```
/msg nickserv identify password NickName
```
To allow NickServ to identify you based on this certificate you need
to associate the certificate fingerprint with your nick. To do this
issue the command cert add to Nickserv (try /msg nickserv helpcert).
```
/msg nickserv cert add
```
