How do you use Testssl?
Run Single Checks Using testssl.sh For example, the -e flag enables you to check each local cipher remotely. If you want to make the test much faster, use include the –fast flag; this will omit some checks, in case you are using openssl for all ciphers, it only displays the first proffered cipher.
What is secure client renegotiation?
The SSL/TLS renegotiation vulnerability is a potential cyber threat in cases when a client can initiate a renegotiation process. An attacker can abuse this situation by making the server unavailable with a Denial of Service attack or can execute a Man-in-the-Middle injection attack into the HTTPS sessions.
