Framework and command-line tool to scan SSL enabled services

Project description

pySSLScan is a framework to scan SSL enabled services, in order to determine the supported ciphers, preferred ciphers, certificate information and more. It is designed to be flexible, lean and fast.

It can be used as a library in other software projects and provides a command-line tool to get started.

You can find more information in the documentation.


  • Query SSL services
  • Supported cryptographic protocols: SSLv2, SSLv3, TLS 1.0, TLS 1.1 and TLS 1.2 (depends on used OpenSSL library)
  • Supported Protocols like TCP, HTTP, SMTP, …
  • IPv4 and IPv6
  • Rule based result highlighting
  • Output formats: text/terminal



  • Python 2.7 or Python >= 3.2
  • Python packages:
    • cryptography >= 0.5
    • pyOpenSSL >= 0.14
    • six >= 1.4.1


At the time of writing pySSLScan requires the development version of the cryptography packages. Use the source directly from the git repository.

$ pip install sslscan


To scan a HTTPS service:

$ pysslscan scan --scan=protocol.http --scan=vuln.heartbleed --scan=server.renegotiation \
  --scan=server.preferred_ciphers --scan=server.ciphers \
  --report=term:rating=ssllabs.2009e --ssl2 --ssl3 --tls10 --tls11 --tls12

To display more information:

$ pysslscan --help
