ChatSecure - Encrypted Messenger

By Chris Ballinger

This app is only available on the App Store for iOS devices.


ChatSecure is a free and open source messaging app that features OTR encryption over XMPP. You can connect to an existing Google account, create new accounts on public XMPP servers (including via Tor), or even connect to your own server for extra security.

Unlike other apps that keep you stuck in their walled garden, ChatSecure is fully interoperable with other clients that support OTR and XMPP, such as Adium, Jitsi, and more.

ChatSecure only uses well-known open source cryptographic libraries to keep your conversations private. Other apps may make claims about 'military grade' security but, without publicly auditable source code and verifiable end-to-end encryption, you cannot be truly safe.

* XMPP with TLS certificate pinning.
* OTR for verifiable end-to-end encryption and forward secrecy.
* OMEMO for a mobile-friendly alternative to OTR.
* Tor integration for easy access to XMPP .onion services.
* SQLCipher to locally encrypt conversation logs.
* Free and Open Source:

What's New in Version 4.1.0

# What's new in 4.1.0
* XEP-0363: HTTP Upload support for much faster and reliable media messaging. [1]
* XEP-0352: Client State Indication. Helps reduce network usage when running in the background.
* End-to-end encryption for file transfers in OMEMO or OTR sessions [2].
* Inline media previews for incoming URLs. (Optional)
* Bug fixes and refactoring.
* Tor

# Caveats
* Your server administrator must enable support for XEP-0363. See mod_http_upload for Prosody [3] and ejabberd [4] for more details.
* Encrypted file transfer is required in OMEMO/OTR, but has limited compatibility for receiving clients. Users on the other end will receive `aesgcm://` links [2].
* Inline media previews are enabled by default, but can be disabled on a per-account basis. This feature should be disabled if you have extreme privacy concerns or do not trust your contacts. This setting is always disabled for Tor accounts.

Customer Reviews

Notifications broken

The notifications never come through. It's hard to see the point of a messenger without working notifications.

No more searching. Best xmpp app for ios

Subj says it all. It can connect through tor without any extra tweaks and external stuff or apps.

And it is free!

XMPP client for iOS

I am a big fan of Signal. It's my go-to...however it sufferers from cross-platform support. This app brings a secure XMPP client to iOS.
