Security-TXT is a simple security.txt library.

>>> from securitytxt import SecurityTXT
>>> sec = SecurityTXT.from_url("")
['', 'mailto:[email protected]']
>>> sec.signature
>>> sec.expired

Security-TXT allows you to easily retrieve, parse and manipulate security.txt files. It tries to follow the latest draft RFC as closely as possible, while it still parses security.txt files that contain minor mistakes. The package is well-documented, thereby easy to use in combination with pydoc:


Security-TXT is not yet available on PyPI. I am currently working on this. The package has only been tested with Python 3.6.8+

Supported Features & Best–Practices

The package has been build to support easy and automated retrieval and parsing of security.txt files. Therefore, features include:

  • Automated searching for security.txt files on specified host.
  • Signature parsing for signed files.
  • Allows for parsing unknown fields and comments that are present in security.txt file.
  • Automated validity tests for parsed security.txt files.
  • Every class and function is fully documented.

Soon to be implemented:

  • fail_silently: if a file format is invalid, it continues parsing the rest of the line instead of raising an error.
