An example implementation of the Triple-Ratchet algorithm, which extends the Double-Ratchet algorithm with a multiparty room context. This is not hardened for production use -- this is for educational purposes only. The Quilibrium codebase will include a hardened version (among other cryptography).

• X3DH consumes a signed identity key, instead of a raw identity key, to maintain key hygiene of the identity key used for signing, and the distinct key used for identity in the X3DH agreement
• All keys are P-256 to be easy to use with hardware and browser cryptography support
• The hashing algorithm used is SHA-3
• It supports multiple parties, not just a two-party context :)
