A WeeChat script that adds Off-the-Record (OTR) encrypted messaging to IRC clients.
weechat-otr is a script for the WeeChat IRC client that adds Off-the-Record (OTR) messaging capabilities. It enables end-to-end encrypted, authenticated private conversations within IRC, providing forward secrecy and deniability to protect user privacy.
IRC users, particularly those using WeeChat, who require secure, private messaging with strong encryption and authentication features.
It integrates OTR encryption directly into WeeChat, offering a seamless, scriptable solution for secure IRC chats without needing external tools, leveraging the trusted Pure Python OTR library.

Implements the Off-the-Record protocol for end-to-end encrypted IRC chats, providing forward secrecy and deniability to protect user privacy, as highlighted in the key features.
Works natively within WeeChat's interface, setting buffer-local variables like otr_encrypted and otr_authenticated for easy status monitoring and integration with other scripts or remote interfaces.
Verifies conversation partner identities to prevent man-in-the-middle attacks, ensuring secure and authenticated private chats directly within IRC.
Uses the Pure Python OTR library for cryptographic operations, leveraging an established and audited codebase mentioned in the README for reliability.
Requires manual installation of the Pure Python OTR package with dependencies like python-dev or build-essential, which can fail and need troubleshooting, as admitted in the README's 'Requirements for building' section.
Only works with WeeChat IRC client, making it unsuitable for users on other clients or those needing cross-platform encrypted messaging solutions beyond IRC.
The README explicitly states it 'offers no guarantee' for security, indicating potential vulnerabilities and the need for user-led auditing, which adds uncertainty for sensitive deployments.
