687804 - Support IRCv3.1 SASL Authentication extension as used on various networks (Mozilla, Freenode)

Status: NEW

(Other Applications :: ChatZilla, enhancement)

Description

[David Vo [:auscompgeek]]

All networks running on charybdis or forks of charybdis, such as ircd-seven (the IRCd that freenode uses), support SASL authentication. This is invoked by using the CAP commands.

Such support has been previously discussed on IRC, and Gryllida has created a plugin for this. However, the plugin is rather hacky.

This bug has several components:
1. Support for the /CAP command (this should be implemented in bug 687798)
2. Actual support for SASL
3. Ways of invoking SASL (URL -> dialog boxes; prefs)
4. If we use prefs, we may also expose this in the Preferences GUI

I'm on freenode and my hostname keeps being shown, the cloak rarely (have it ever?) active in time for Chatzilla auto-rejoining. If SASL can't be implemented, can there be some option to delay the rejoin?

Rejoin is a pretty sweet feature, I tried a popular client for a few days, as I kept forgetting to open Chatzilla when FF loaded, and came back because the former wouldn't rejoin on reconnect.

A specification of the SASL protocol can be found at <http://ircv3.atheme.org/extensions/sasl-3.1>. An implementation in the form of a ChatZilla plugin written by Svetlana can be found at <http://freenode.net/sasl/cz_sasl.js>.

After discussion with Svetlana offline (see comment 2), the cz_sasl.js script has been licensed under MPL2 and thus may be used as a starting point for SASL integration into Chatzilla if so desired.

Attached is cz_sasl-0.6.3.js with the observed MPL2 license (and various changelogs) for posterity.

Updating description as we use SASL at Mozilla now, too.
