• Added a a pre-built Windows executable: sslyze-3.0.1-exe.zip.

3.0.0

Big internal refactoring focused on modernizing the code base (dataclasses, type annotations, etc.) and improving the speed and reliability of the scan results.

• The Python API and the format of the outputs have been drastically improved and simplified, but are not backward-compatible with older versions of SSLyze.
• Python 3.8 is now supported, and Python 3.6 is no longer supported.
• Huge improvements to the reliability of the scans:
  • The number of concurrent connections per single server can now be controlled and is set to 5 by default (#385).
  • This limit is enforced regardless of the number of scan commands queued for the server, and drastically reduces the number of scans that fail due to a slow server or a slow connection.
• Various improvements to cipher suites scanning:
  • The size of the cipher's suite key is now always returned.
  • The (EC) Diffie-Helmann parameters negotiated during the TLS handshake are now returned (#394).
• Various improvements to server certificate checks:
  • Servers that expose multiple leaf certificates and chains are now supported (#326).
  • Bug fix for Symantec CA deprecation (#406).
• SSLyze is now compatible with PEP 561 for type checking with mypy.
• Various improvements to the JSON output:
  • The format of the JSON output now exactly matches the format of the Python output (which is fully documented).
  • Better parsing of Subject and Issuer fields in certificates (#404).
• Support for XML output was removed.

2.1.4

• Fixed crash when scanning servers that only support old versions of SSL/TLS (#386).

2.1.3

• Tweaked the ROBOT check to reduce the chance SSLyze returning a false positive.
