​​A year ago, AWS acquired the world's most secure messenger, Wickr.

And now another product — AWS Wickr: 🎉

https://aws.amazon.com/wickr/

AWS Wickr encrypts every message, call, and file with a proprietary, 256-bit end-to-end encryption (E2EE) protocol. No one but intended recipients can decrypt them, reducing the risk of person-in-the-middle (PitM) attacks.

End-to-End Encryption
☐ Wickr provides secure communication between two or more correspondents. It means that the system provides authenticity and confidentiality: no unauthorized party can inject a message into the system, and no unintended party can access or understand the communications without being given them by one of the correspondents.
☐ Each message gets a unique AES encryption key and a unique ECDH public key to negotiate the key exchange with other recipients. The message content (text, files, audio, or video) is encrypted on the sending device (your iPhone, for example) using the message-specific AES key. The message-specific AES key is exchanged with recipients via a Diffie-Hellman EDCH521 mechanism. This ensures that only intended recipients have the message-specific AES key to decrypt the message.
