Introduction

SKISSM implements the Signal protocol and aims to make it easy to build versatile end-to-end messaging applications. The two crucial security properties provided:

• End-to-end encryption

  Only sender and recipient (and not even the server) can decrypt the content.

• Forward secrecy

  Past sessions are protected against future compromises of keys or passwords.
