The protocol was developed by Open Whisper Systems in 2013 and was first introduced in the open-source TextSecure app, which later became Signal. Signal's privacy policy states that recipients' identifiers are only kept on the Signal servers as long as necessary in order to transmit each message. Signals is recommended by Edward Snowden or Bruce Schneier, one of the most popular whistleblowers of the decade. Further reading Privacy isn’t an optional mode — it’s just the way that Signal … The TextSecure protocol was originally a derivative of OTR, with minor changes to accommodate it for transports with constraints like SMS or Push.Some of the recent changes we’ve made include simplifying and improving OTR’s deniability, as well as creating a … [4] Facebook Messenger also say they offer the protocol for optional Secret Conversations, as does Skype for its Private Conversations.

[22] In June 2016, Moxie Marlinspike told The Intercept: "the closest piece of information to metadata that the Signal server stores is the last time each user connected to the server, and the precision of this information is reduced to the day, rather than the hour, minute, and second. Moreover, WhatsApp uses the same E2E protocol as Signal, developed by Open Whisper Systems. X3DH establishes a shared secret key between two parties who mutually authenticate each other based on public keys. [2] The protocol was developed by Open Whisper Systems in 2013[2] and was first introduced in the open-source TextSecure app, which later became Signal. [6][7] Among other findings, they presented an unknown key-share attack on the protocol, but in general, they found that it was secure. Moxie Marlinspike, founder of Open Whisper Systems (OWS), the not-for-profit software group behind the respected Signal Protocol crypto (and the eponymous Signal secure messaging app) has responded to Open Whisper Systems uses your contacts database for contact discovery. [31][32][33][34], In September 2015, G Data Software launched a new messaging app called Secure Chat which used the Signal Protocol.
