Usage

headerpwn allows you to test various headers on a target URL and analyze the responses. Here’s how to use the tool:

Provide the target URL using the -url flag. Create a file containing the headers you want to test, one header per line. Use the -headers flag to specify the path to this file.

Example usage:

headerpwn -url https://example.com -headers my_headers.txt
Format of my_headers.txt should be like below: Proxy-Authenticate: foobar
Proxy-Authentication-Required: foobar
Proxy-Authorization: foobar
Proxy-Connection: foobar
Proxy-Host: foobar

Export Burp’s Certificate:

Install Burp’s Certificate:

Install the exported certificate as a trusted certificate on your system. How you do this depends on your operating system. On Windows, you can double-click the .cer file and follow the prompts to install it in the “Trusted Root Certification Authorities” store. On macOS, you can double-click the .cer file and add it to the “Keychain Access” application in the “System” keychain.

You should be all set:

headerpwn -url https://example.com -headers my_headers.txt -proxy 127.0.0.1:8080
