Basic Auth Header Guide
Build an HTTP Basic Authorization header from a user and password.
A short companion for Basic Auth Header: when it is useful, what it expects, and what to check before using the result.
What it does
Build the Authorization: Basic header value from a username and password, and optionally produce a ready-to-use curl command. The encoding is plain Base64, which is exactly why it is only safe over HTTPS.
Use the tool
Open Basic Auth Header, add the input the tool asks for, run it, and check the output before using it elsewhere.
Input and output
- Input: text.
- Output: text.

Privacy and processing
Processing happens locally in your browser. This tool does not upload the input to ilham.dev.
Questions
Is Basic authentication encrypted?
No. The credentials are Base64-encoded, which anyone can reverse. They are protected only by the TLS connection carrying them, so never use it over plain HTTP.
