Package: headerexposer
HeaderExposerAnalyse the security of your website’s headers!The headerexposer module provides functions to analyse the security
of a website’s headers.It can be loaded as a module, or directly ran from the commandline.It is designed to be cross-platforms, and was tested in various Linux/Windows terminals.RequirementsThese requirements will automatically be installed upon headerexposer's installation with pip.ansiwrap: The standard textwrap module does not support ANSI codes, hence the use of ansiwrap as a replacement.colorama: This is only used for color compatibility on Microsoft platforms.jsonschema: This is used for json validation.requests: Used in the module's CLI for performing HTTP requests.tabulate: Used for printing nice tables.urllib3: (normally a dependency of requests) This is only used to intentionally suppress a specific warning.InstallationLet pip take care of everything:python -m pip install headerexposerCLI UsageGlobal usage:usage: headerexposer [-h] [-b BASELINE_PATH] [-s] [--no-explanation-colors]
