You can check which HTTPS protocols and ciphers are enabled on your Cloudmersive Private Cloud Server. This is often needed for security inventory purposes. Note that all HTTPS termination in Cloudmersive Private Cloud Server is handled by Internet Information Server.

Check ciphers

To check the available ciphers, you can use an open source tool called OpenSSL for Windows. To check your ciphers, you can run this command from a command prompt on the server or from a remote client:

openssl s_client -connect yourserver.com:443 -cipher 'ALL:eNULL' 

You will want to replace yourserver.com with the host name of your Private Cloud Server.

Check protocols

To check the available protocols, you can use an open source tool called OpenSSL for Windows. To check your protocols, you can run this command from a PowerShell window on the server or from a remote client:

$server='yourserver.com'; $port=443; $protocols=@('ssl3', 'tls1', 'tls1_1', 'tls1_2', 'tls1_3'); foreach($protocol in $protocols) { echo "$protocol: "; echo | & 'openssl' s_client -connect "$($server):$($port)" -$protocol 2>&1 | Select-String -Pattern "Protocol  :" }

You will want to replace yourserver.com with the host name of your Private Cloud Server.
