WeeChat's IRC support includes multiple servers, proxies, IPv6 and SASL. SASL addresses authentication; it should not be described as end-to-end encryption for the conversation.
For the WeeChat alternatives entry, configure a test connection using the network's documented secure transport and authentication settings. Reconnect and verify the expected identity before joining channels. Evaluate notification and buffer navigation separately from the security properties supplied by the network and client configuration.
