SASL ECDSA-NIST256P-CHALLENGE

By Sébastien Helleu on Sunday, February 8 2015, 20:19 - irc

The support of a new SASL mechanism called "ecdsa-nist256p-challenge" has been added three weeks ago.
This new mechanism uses a challenge with public/private key, so no password is required to connect.

Instructions to configure and use this mechanism are in user's guide: https://weechat.org/doc/devel/user/en/#irc_sasl_authentication.

Important notes:

  • GnuTLS ≥ 3.0.21 is required.
  • This mechanism can only be used on servers supporting it (for example servers using atheme, like freenode).

SASL authentication with IRC server

By Sébastien Helleu on Friday, February 19 2010, 17:54 - irc

It is now possible to use SASL authentication with IRC server, using two mechanisms: "plain" (default) or "dh-blowfish" (crypted password).

New options have been added to servers:

  • sasl_mechanism: mechanism to use ("plain" or "dh-blowfish")
  • sasl_timeout: timeout (in seconds) for authentication
  • sasl_username: username
  • sasl_password: password

You just have to setup username (your nick) and password (password of nick) and then connect to server, you'll be identified with SASL if all is ok.

If you want to set "dh-blowfish" by default for all servers:

/set irc.server_default.sasl_mechanism dh-blowfish
