inSync Master Server 5.9.8 does not support Forward Secrecy

Heads up!

We've transitioned to a new documentation portal to serve you better. Access the latest content by clicking here.

This article applies to:

  • OS: All supported operating systems
  • Product edition: inSync On-Premise

Problem description

Forward secrecy (also called perfect forward secrecy) is a protocol feature that enables secure conversations that are not dependent on the private key of the server. With cipher suites that do not provide forward secrecy, someone who can recover a server’s private key can decrypt all the encrypted conversations recorded earlier. inSync must support and prefer ECDHE suits to enable forward secrecy with the modern web browsers. To support a wider range of clients, DHE suits must be used as a fall back after ECDHE to enable forward secrecy with the modern web browsers.
