The privacy page and the privacy and security whitepapers explain the details of the encryption algorithms and protocols used.

For licensing information, see the attached LICENSE file and the list of third-party licenses at wire.com/legal/licenses/.

If you compile the open source software that we make available from time to time to develop your own mobile, desktop or web application, and cause that application to connect to our servers for any purposes, we refer to that resulting application as an “Open Source App”. All Open Source Apps are subject to, and may only be used and/or commercialized in accordance with, the Terms of Use applicable to the Wire Application, which can be found at https://wire.com/legal/#terms. Additionally, if you choose to build an Open Source App, certain restrictions apply, as follows:

a. You agree not to change the way the Open Source App connects and interacts with our servers; b. You agree not to weaken any of the security features of the Open Source App; c. You agree not to use our servers to store data for purposes other than the intended and original functionality of the Open Source App; d. You acknowledge that you are solely responsible for any and all updates to your Open Source App.

For clarity, if you compile the open source software that we make available from time to time to develop your own mobile, desktop or web application, and do not cause that application to connect to our servers for any purposes, then that application will not be deemed an Open Source App and the foregoing will not apply to that application.

Components

AVS

The audio, video, and signaling (AVS) library of Wire is developed in ANSI C/C++. The code is cross compiled for Android and iOS. Wrappers for interaction with upstream modules are written in Java for Android and Objective-C for iOS.

Repositories

avs: Audio-video library for calling (mostly C), then cross compiled for iOS and Android

Proteus/Cryptobox

The Axolotl protocol implementation and other cryptographic and utility libraries are developed in Rust, then cross-compiled for iOS and Android. The web version has its own port of these libraries in JavaScript.

Repositories

proteus: Axolotl Protocol Implementation in Rust, then cross compiled for iOS and Android
cryptobox: High-level API with persistent storage for proteus
cryptobox-haskell: Haskell bindings to cryptobox
cryptobox-c: C-FFI to cryptobox
hkdf: HKDF implementation (RFC 5869) in Rust, then cross compiled to iOS and Android

Common definitions

Protocol buffer definitions are used by all clients to communicate with each other and with the backend.

Repositories

generic-message-proto: Protocol buffer definitions that are part of the cross-platform client communication protocol
backend-api-protobuf: Protocol buffer definitions that are part of the backend communication protocol
