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
  • DTLS 1.0 and DTLS 1.2
• Supported Protocols:
  • TCP, HTTP, IMAP, POP3, SMTP, LDAP and RDP
  • UDP
• IPv4 and IPv6
• Scan modules:
  • Supported ciphers
  • Ciphers preferred
  • Supported compression methods
  • Supported elliptic curves
  • Test support for Signaling Cipher Suite Value (SCSV)
  • Extract EC Point Formats
  • Server certificate (requires pyOpenSSL)
  • Test renegotiation (requires pyOpenSSL)
  • Detect vulnerabilities
    • Heartbleed
  • Extract server information: HTTP, IMAP, POP3 and SMTP
• Rule based result highlighting
• Output formats:
  • text/terminal

Requirements:

• Python 2.7 or Python >= 3.2
• Python packages:
  • flextls >= 0.3
  • six >= 1.4.1
• Python packages(optional):
  • cryptography >= 0.5
  • pyOpenSSL >= 0.14

Install:

At the time of writing pySSLScan requires the development version of the cryptography packages. Use the source directly from the git repository. https://github.com/pyca/cryptography

$ 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 http://example.org

$ pysslscan --help
