OpenSSL 4 within a browser

The CrypTool project ported the newly released OpenSSL 4.0.0 ("OpenSSL 4.0 Final Release – Live") within one week to WebAssembly (like done before with OpenSSL versions 3.0, 3.5, and 3.6).

So now, OpenSSL can be used freely and without advertising from inside a browser.

At this website you see below the black terminal a GUI (graphical user interface) with 6 tabs which offer easy access for those who want to learn OpenSSL CLI commands. "CLI" means command-line interface, often just called terminal.

When you click on "Run" for a selection in the GUI, the according OpenSSL command will be shown and performed. So depending on your experience, you can either type the OpenSSL command directly in the terminal, or you can walk through the GUI and find out what to do by just click and paste.

CrypTool is an open-source project creating the most widespread free elearning programs for cryptography and cryptanalysis. It is mostly used by students, lecturers and in awareness trainings worldwide, and it is available in English and German.

If you want to test and use it — and give us feedback, we'd really appreciate that.
