ChatSecure Messenger vs StealthTalk Private Messenger

ChatSecure is a free and open source messaging app that features OTR and OMEMO encryption over XMPP. You can create new accounts on public XMPP servers, 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, OMEMO and XMPP. 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. * SQLCipher to locally encrypt conversation logs. * Free and Open Source: https://github.com/chatsecure/chatsecure-ios Follow @ChatSecure on Twitter: https://twitter.com/chatsecure ►► ChatSecure Donations Subscribe to ChatSecure to help make developing free and open source privacy tools sustainable.
