Text messages and pictures use the Proteus protocol for end-to-end encryption. Proteus is based on the Axolotl ratchet and pre-keys that are optimized for mobile and multi-device messaging.
Voice and video calls use the WebRTC standard. More precisely, DTLS and KASE are used for key negotiation and authentication and SRTP is used for encrypted media transport. This means that voice calls are end-to-end encrypted with perfect forward secrecy enabled without compromising HD call quality.
Wire’s encryption works transparently in the background and doesn’t need to be activated — it’s always on. There’s no need to compromise security for usability or settle for missing features. Wire keeps everything private while avoiding the complexity that is common to other secure messengers.
We store only the data we need to make sure your conversations stay in sync across devices, to detect fraud and spam, and to troubleshoot customer issues.
Wire’s source code is available on GitHub with a GPLv3 licence.
A self-hosted server option will be available in 2018.
Wire publishes a regular transparency report detailing all lawful requests for user data.
Wire does not sell or share its users’ data. We make money from paying customers and don’t rely on donations.
Wire is committed to working with independent security experts to publish regular audits of different components of our app.
