Product Information
What is Chatsecure?
ChatSecure is a free and open-source messaging application featuring OTR encryption over XMPP. You can connect to existing accounts on Facebook or Google, create new accounts on public XMPP servers (including via Tor), or even link to your own server for enhanced security.
Unlike other apps that confine you within walled gardens, ChatSecure is fully interoperable with other clients supporting OTR and XMPP, such as Adium, Jitsi, and more. It exclusively employs well-known open-source encryption libraries to safeguard the privacy of your conversations. While other apps may boast "military-grade" security, without publicly auditable source code and verifiable end-to-end encryption, true security remains unattainable.
Features:
- XMPP with TLS certificate pinning.
- OTR for verifiable end-to-end encryption and forward secrecy.
- OMEMO as a mobile-friendly alternative to OTR.
- Tor to bypass restrictive firewalls.
- SQLCipher for locally encrypted conversation logs.
