TLS-Scanner is a tool created by the Chair for Network and Data Security from the Ruhr-University Bochum to assist pentesters and security researchers in the evaluation of TLS Server configurations.

Please note: TLS-Scanner is a research tool intended for TLS developers, pentesters, administrators and researchers. There is no GUI. It is in the first version and may contain some bugs.

In order to compile and use TLS-Scanner, you need to run:

$ cd TLS-Scanner
$ git submodule update --init --recursive
$ mvn clean package

Alternatively, if you are in a hurry, you can skip the tests by using:

$ mvn clean package -DskipTests=true

If you want to use TLS-Scanner as a library you need to install it with the following command:

$ mvn clean install

In order to run TLS-Scanner you need to run the jar file in the apps/ folder.

$ java -jar apps/TLS-Server-Scanner.jar -connect localhost:4433

You can specify a host you want to scan with the -connect parameter. If you want to improve the performance of the scan you can use the -threads parameter (default=1).

We provide you with a Dockerfile, which lets you run the scanner directly:

$ docker build . -t tlsscanner
$ docker run -t tlsscanner

Please note: I am by no means familiar with Docker best practices. If you know how to improve the Dockerfile feel free to issue a pull request
