TLS Check ​

The TLS Check checks a web server for accepted and supported TLS versions. It tries to establish a connection with different TLS versions. If desired, different algorithms can be tested, but this increases the runtime of the check.

It is important to note that if OpenSSL is installed on the used device, the connection is established by the device directly, else the connection is established by a server located in Germany.

The resulting OpenSSL commands are :

openssl s_client -connect $hostname:$port -$tlsVersion

openssl s_client -connect $hostname:$port -$tlsVersion

If check cipher suites is activated the resulting OpenSSL command is :

openssl s_client -connect $hostname:$port -$tlsVersion -ciphersuites '$suite'

openssl s_client -connect $hostname:$port -$tlsVersion -ciphersuites '$suite'

The available cipher suites are taken from :

openssl ciphers -v

openssl ciphers -v
