Free and open source encrypted chat for iOS.


ChatSecure v2.2 Released

ChatSecure v2.2 for iOS was approved by Apple today. One of the main new features is support for SSL certificate pinning, to help prevent man-in-the-middle attacks. A nice side effect of implementing this feature is that we now support alternative root CAs like, which now means accounts should work properly. This also means that if you run your own XMPP server with a self-signed certificate, you should have less problems connecting and can now verify and pin the SHA1 hash of your certificate before connecting. @davidchiles crafted a beautiful and simple interface that appears for each new certificate, including information about whether or not the certificate would pass the built-in iOS certificate checks:
