Tor: Bridge validity check (CLI)

Tor ([login to view URL](anonymity_network)) can be used with bridges, which gives the ability to circumvent censorship. The lifetime of these bridges is sometimes not too long, which is why it can be advantageous to check the functionality of used bridges and then activate or deactivate them. For that purpose, there is the following platform (Metrics): [login to view URL]

On Metrics, the bridge's can be tested with the fingerprint of a bridge (for example: 6743F2AA0F9BD302AFD1AE41F83D5FE1C70159CE).

What do I need?

A Linux program that runs in a terminal (CLI) and returns a 0, 1, or 2 based on the result of a tested fingerprint of the bridge (input). The response of the program has to indicate whether the bridge is online, offline (green or red dot on Metrics), or not in the database at all (no results found!). This program is used for a bash script, which means that no graphical interface is available.

Additional requirements

- Binary and source code of the program with comments have to be available.

If you are interested in this task, then briefly outline to me in your proposal how you want to tackle it. I'm also open to your additional questions and suggestions.
