Is your Data protected?
Nowadays we store important data on our notebooks and often we use portable USB devices to transport data. What happens if you lose these devices? Symmetric encryption with symmetric key can protect you from others being able to use your data. Encryption and Decryption can help you. But what is encryption? Modern encryption (known as cryptography) secures sensitive Information (digital data) using symmetric and asymmetric algorithms. But don’t worry. Just use the right encryption software.

The online course „Introduction to Encryption“ shows you why we encrypt our data and how the complex elements of cryptography are connected. What is encryption and how can it help you? Each of us has confidential data that is worth protecting. In the practical exercises I’ll show you online which tools you can use to encrypt your confidential data quickly and free of charge, so that no one other than yourself can access it.

In this video we look at how encryption and decryption is used for Confidentiality. This type of encryption is very complex, as it uses both symmetric and asymmetric encryption. In general, this process is called hybrid encryption. How important is the symmetric key in this context? Why is asymmetric encryption used here?

In this video I will explain how Authenticity works with a digital certificate. A digital certificate can be used to uniquely identify the author of the message. All necessary information is stored there and digitally signed. Only if the signature is valid, then we can trust the certificate. But who issued the digital certificate to the owner? Can we trust the CA, whose private key was used to sign the certificate?

FIDO2 is a protocol for a new, modern, simple, phishing-proof, passwordless authentication
between servers, browsers and authenticators,such as the Yubikey 5 or NitroKey 3.
The abbreviation FIDO stands for Fast IDentity Online and is also called FIDO Alliance. This
Alliance is a consortium that develops secure, open, phishing proof, passwordless authentication standards.
In this video we’re looking at how 2 factor authentication works using Security Key
and why is FIDO an important technology for this.

STUDENT FEEDBACK
“Encryption is not a simple topic. This course makes it easy to use. The professionally animated videos taught me the basics and kept me focused”
“Most courses on encryption are rather boring because often only PowerPoint slides are shown. This course is quite different. With special icons and graphics I could navigate very well in the topic.”
