      A complete implementation of XEP-0384 on protocol-level, i.e. more than just the cryptography.
      python-omemo supports different versions of the specification through so-called backends.

      A backend for OMEMO in the urn:xmpp:omemo:2 namespace (the most recent version of the specification) is available
      in the python-twomemo Python package.
      A backend for (legacy) OMEMO in the eu.siacs.conversations.axolotl namespace is available in the python-oldmemo
      package.
      Multiple backends can be loaded and used at the same time, the library manages their coexistence transparently.
