Open-source messaging platform

Optional end-to-end encryption is silly, why would I ever want there to be a possibility for my messages to be read by someone other than the person I'm sending it to? It shouldn't have to be something you turn on. Also it's only available for enterprise.

TextSecure and Signal by Open Whisper System are better https://whispersystems.org/

Use anything by Open Whisper Systems.

- Edward Snowden, Whistleblower and privacy advocate

Signal is the most scalable encryption tool we have. It is free and peer reviewed. I encourage people to use it everyday.

- Laura Poitras, Oscar winning filmmaker and journalist

I am regularly impressed with the thought and care put into both the security and the usability of this app. It's my first choice for an encrypted conversation.

- Bruce Schneier, internationally renowned security technolgist

After reading the code, I literally discovered a line of drool running down my face. It’s really nice.
