# testssl.sh: check a server’s TLS protocols



Check a server’s TLS protocols.



## 1. Run the example



[Download the testssl.sh example](https://www.security.run/docs/examples/testssl.zip). Extract it, install `httpx`, set your API URL and token, then run `python client.py`. The client uploads the included inputs, submits the command, and saves the result under `results/RUN_ID`.



## 2. Check the result



Read report.json for protocol results from the isolated TLS target.



Read the native exit code and cleanup status printed by the client. [Read results and save reports](https://www.security.run/docs/visibility.html) explains the returned files.



## 3. Use your own inputs



Edit `example.json` to change the command arguments, requested outputs or deadline. Replace the files under `inputs/` with your own data, keeping the staged paths aligned with the command. The client creates the artifact IDs for you; illustrative IDs shown here must not be copied into a live request.



This example selects the isolated `tls-fixture` target. To use a reachable target of your own, change the target arguments or driver and remove `target_profile`. See [Run a check against a target](https://www.security.run/docs/targets.html) for network setup.



Qualified version: `3.2.5`. Commands: `testssl`.



Inspect `GET /v1/tools/testssl` for the current installed version and readiness. The published snapshot has 1 functional case(s), plus timeout and cancellation checks. These examples demonstrate the native path; other flags and inputs are supported within the tool’s runtime limits.
