Let's Use AES in CrypTool 2 to Encrypt Files Using a Password

#cryptology, #cryptography, #cryptanalysis I was asked several times, how to encrypt (and decrypt) files securely using CrypTool 2. Therefore, in this video, I explain how to encrypt/decrypt files using CrypTool 2. We use the Advanced Encryption Standard (AES) cipher for encryption and decryption. To create a cryptographic key based on a password we use the HKDF key derivation function. In the end of the video, we have three different CT2 workspaces: 1) for text en- and decryption, 2) for file encryption, and 3) for file decryption. If you are interested in learning the basics of cryptology, you should also have a look at our video series about basics of cryptology – also for beginners: https://youtu.be/jbumW7Ym03o You may download the latest version of CrypTool 2 from here: https://www.cryptool.org/en/ct2/downloads Like what I do 😄?
