# Carbon
Carbon is a tool that issues HTTP requests, then parses, sorts and displays relevant HTTP response headers.
> **NOTE**: The name 'carbon' comes from carbon filtering: method of filtering impurities.
By default it will display all response headers with coloured keys, but headers can also be filtered, as well as parsed into JSON for easier piping/analysis...

## Tests?
Nope. This was just a quick hack
## Bash Alternative?
Here's an official repo for the [Bash version](https://github.com/Integralist/Bash-Headers) (if you're interested, although it's a lot more basic but was the starting point that motivated me to do this go version).
