What is SSL renegotiation?

A number of Internet connections require SSL renegotiation, a Secure Sockets Layer/Transport Layer Security process that allows the changing of the details of a handshake after a connection is made with the server.

How do you test for secure renegotiation?

The idea is that you connect to an SSL server and start by typing the first line of a request. You then type a single uppercase letter R on a single line, which tells OpenSSL to ask for renegotiation. I am aware of the following outcomes: Your HTTP request completes, which means that renegotiation is enabled.

How do you know if a cipher is weak?

Identify Weak Protocols and Cipher Suites

  1. Identify traffic that uses less secure TLS protocol versions.
  2. Identify traffic that uses a particular key exchange algorithm.
  3. Identify traffic that uses a particular authentication algorithm.
  4. Identify traffic that uses a particular encryption algorithm.
