Must be globally enabled in Advanced Settings as well as individually for each group chat. 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.

ChatSecure + Orbot Review

I love Chat but this latest update crashes constantly! The biggest problem Is when I scroll back through my texts and in the middle of that the whole thing crashes! Encrypted, easy to use, and in today's subscription plan world full functionality and a donate button. This app should be your go to for xmpp. The notifications never come through.

It's hard to see the point of a messenger without working notifications. This app is only available on the App Store for iOS devices. Must be globally enabled in Advanced Settings as well as individually for each group chat. What's new in 4. HTTP Upload support for much faster and reliable media messaging.

Helps reduce network usage when running in the background. 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. What's new in v4. Now you can support continued development via in-app purchase. Help make developing free and open source privacy tools sustainable!

Automatically create new account, move existing contacts, archive old conversations, and optionally notify old contacts of new account info. In addition to swipe-to-delete, there is now swipe-to-archive, which allows decluttering the inbox without deleting conversation history.

If your outgoing OMEMO messages were no longer getting delivery receipts, send some messages back and forth and it should fix the issue. When you receive an undecipherable message it will clear the session, which allows the session to be re-initiated on your next outgoing message. This keeps track of the last time you interact with the app, and will report this value when queried by your contacts.

The time you last interacted with the app is identical for all of your accounts, so broadcasting this value is disabled for Tor accounts and when auto-login disabled.

TextSecure allowed the user to set a passphrase that encrypted the local message database and the user's encryption keys. TextSecure had a built-in function for verifying that the user was communicating with the right person and that no man-in-the-middle attack had occurred. This verification could be done by comparing key fingerprints in the form of QR codes in person. TextSecure allowed users to chat with more than one person at a time. The servers did not have access to group metadata such as lists of group members, the group title, or the group avatar icon.

The application could also function as a drop-in replacement for Android's native messaging application as it could fall back to sending unencrypted SMS and MMS messages.

TextSecure required that the user had a phone number for verification. A number could only be registered to one device at a time. TextSecure was the first application to use the Signal Protocol then called the TextSecure Protocol , which has since been implemented into WhatsApp , Facebook Messenger , and Google Allo , encrypting the conversations of "more than a billion people worldwide".

The protocol provides confidentiality, integrity, authentication, participant consistency, destination validation, forward secrecy , backward secrecy aka future secrecy , causality preservation, message unlinkability, message repudiation, participation repudiation, and asynchronicity.

The group chat protocol is a combination of a pairwise double ratchet and multicast encryption. All client-server communications were protected by TLS. In order to determine which contacts were also TextSecure users, cryptographic hashes of the user's contact numbers were periodically transmitted to the server.

The group messaging mechanism was designed so that the servers did not have access to the membership list, group title, or group icon. The server architecture was partially decentralized between December and February In December , it was announced that the messaging protocol that was used by TextSecure had successfully been integrated into the Android-based open-source operating system CyanogenMod.

According to Open Whisper Systems, the Cyanogen team ran their own TextSecure server for WhisperPush clients, which federated with Open Whisper Systems' TextSecure server, so that both clients could exchange messages with each-other seamlessly. The complete source code of TextSecure was available on GitHub under a free software license. TextSecure was officially distributed only through Google Play.

TextSecure was briefly included in the F-Droid software repository in , but was removed at the developer's request because it was an unverified build and exceptionally out of date. Open Whisper Systems have subsequently said that they will not support their applications being distributed through F-Droid because it does not provide timely software updates, relies on a centralized trust model and necessitates allowing the installation of apps from unknown sources which harms Android's security for average users.

In October , iSEC Partners published a blog post in which they said that they had audited several of the projects supported by the Open Technology Fund over the past year, including TextSecure. TextSecure was developed by a nonprofit software group called Open Whisper Systems. As of October [update] , the project has received an unknown amount of donations from individual sponsors via the Freedom of the Press Foundation. From Wikipedia, the free encyclopedia.
