libomemo_c

Descrizione

This is a fork of libsignal-protocol-c, an implementation of Signal's ratcheting forward secrecy protocol that works in synchronous and asynchronous messaging. The fork adds support for OMEMO as defined in XEP-0384 versions 0.3.0 and later. - OMEMO version 0.3.0 uses the original libsignal-protocol-c implementation with its protocol versions 2 and 3. - OMEMO version 0.4.0+ is implemented using a new protocol version 4 internally.

In comparison with protocol version 3, it changes: - HKDF info strings - Protocol buffer encoding - Signature scheme (uses XEd25519 instead of custom "Curve25519 signatures") - Specification-compliant double ratchet - Support for Ed25519 public keys - Various serializations - Removes unused functionality
