#### Testing TLS/SSL encryption anywhere on any port

testssl.sh is a free command line tool which checks a server's service on
any port for the support of TLS/SSL ciphers, protocols as well as some
cryptographic flaws.

Key features:

* Clear output: you can tell easily whether anything is good or bad.
* Machine readable output (CSV, two JSON formats)
* No need to install or to configure something. No gems, CPAN, pip or the like.
* Works out of the box: Linux, OSX/Darwin, FreeBSD, NetBSD, MSYS2/Cygwin, WSL (bash on Windows). Only OpenBSD needs bash.
* A Dockerfile is provided, there's also an offical container build @ dockerhub.
* Flexibility: You can test any SSL/TLS enabled and STARTTLS service, not only web servers at port 443.
* Toolbox: Several command line options help you to run *your* test and configure *your* output.
* Reliability: features are tested thoroughly.
* Privacy: It's only you who sees the result, not a third party.
* Freedom: It's 100% open source. You can look at the code, see what's going on.
* The development is open (github) and participation is welcome.

## Enable snaps on Kubuntu and install testssl

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.

Snaps are discoverable and installable from the [Snap Store](https://snapcraft.io/store), an app store with an audience of millions.

### Enable snapd

If you’re running [Kubuntu 16.04 LTS (Xenial Xerus)](https://kubuntu.org/) or later, including [Kubuntu 18.04 LTS (Bionic Beaver)](https://wiki.ubuntu.com/BionicBeaver/ReleaseNotes/Kubuntu) and [Kubuntu 18.10 (Cosmic Cuttlefish)](https://wiki.ubuntu.com/CosmicCuttlefish/ReleaseNotes/Kubuntu), you don’t need to do anything. Snap is already installed and ready to go.

Versions of Kubuntu between [14.04 LTS (Trusty Tahr)](https://kubuntu.org/news/kubuntu-14-04-lts) and [15.10 (Wily Werewolf)](https://kubuntu.org/news/kubuntu-15-10) don’t include *snap* by default, but *snap* can be installed from the command line as follows:

```
sudo apt update
sudo apt install snapd
```
