CipherScan:- Discovers the SSL ciphersuites supported by the target.



  • Tests the ordering of SSL/TLS ciphers.
  • Extracts information on


               TLS options

               OCSP stapling


Supported Operating System

  • Unix
  • Linux
  • Darwin








-a | --allciphers                                  Test all known ciphers individually at the end

-b | --benchmark                              Activate benchmark mode.

--capath                                              Use cas from directory (must be in openssl cadir format)

OpenSSL Options

-starttls [smtp|imap|pop3|ftp|xmpp]

Enable support and testing of the protocols that require turning TLS after initial protocol specific.

-servername name                         

Request SNI support for connections

-proxy proxyhost:port                   

Connect to the scan target via specified proxy     (req. OpenSSL 1.1.0 or bundled OpenSSL)

-verify_hostname name               

Request host name verification in connection      (req. OpenSSL 1.0.2)

-verify_ip ip      

Request host name verification for an IP address, usually not specified in certificates (req. OpenSSL 1.0.2)


Analysing Configurations

The motivation behind CipherScan is to help operators configure good TLS on their endpoints. To help this further, the script compares the results of a CipherScan with the TLS guidelines and output a level and recommendations.
