F5-Labs / cryptonice

CryptoNice is both a command line tool and library which provides the ability to scan and report on the configuration of SSL/TLS for your internet or internal facing web services. Built using the sslyze API and ssl, http-client and dns libraries, cryptonice collects data on a given domain and performs a series of tests to check TLS configuration and supporting protocols such as HTTP2 and DNS.

Some sites not returning TLS/certificate info despite TLS being available #45

Open warburtr0n opened 3 years ago

warburtr0n commented 3 years ago

For example buzzfeed.com

cryptonice buzzfeed.com --scans tls dns http jarm --tls all

Traceback (most recent call last):
  File "/var/task/lambda_function.py", line 55, in lambda_handler
    output_data, hostname = scanner.scanner_driver(input_data)
  File "/opt/python/lib/python3.7/site-packages/cryptonice-1.3.7.1-py3.7.egg/cryptonice/scanner.py", line 453, in scanner_driver
    cert_fingerprint = tls_data['certificate_info']['certificate_0']['fingerprint']
KeyError: 'certificate_info'

This one is simply that the certificate_info key isn’t set.
That’s likely due to tls_data = tls_scan(ip_address, str_host, commands_to_run, port) not always setting it.

Although Cryptonice v1.4.0.1 isn't producing an error, it is producing odd outputs. i.e. TLS is available and a TLS fingerprint is available, but not cipher, protocol or cert info is available:
