Signal conversations are always end-to-end encrypted, which means that they can only be read or heard by your intended recipients. Privacy isn’t an optional mode — it’s just the way that Signal works. Every message, every call, every time. You can confirm that the server is operating correctly and that you are communicating with the right person using safety numbers.
The complete source code for the Signal clients and the Signal server is available on GitHub. This enables interested parties to examine the code for security and correctness.
