Double Ratchet Algorithm - Wikipedia
In cryptography, the Double Ratchet Algorithm (previously referred to as the Axolotl Ratchet ) is a key management algorithm that was developed by Trevor Perrin and Moxie Marlinspike in 2013. It can be used as part of a cryptographic protocol to provide end-to-end encryption for instant messaging. After an initial key exchange it manages the ongoing renewal and maintenance of short-lived session keys. It combines a cryptographic so-called "ratchet" based on the Diffie–Hell… Web2key-ratchet. 2key-ratchet is an implementation of a Double Ratchet protocol and X3DH in TypeScript utilizing WebCrypto. The Double Ratchet protocol and X3DH were designed with goals of providing both forward secrecy and cryptographic deniability. Importantly there have been several independent security reviews that concluded they deliver on ...
