About this video

#cryptology, #cryptography, #cryptanalysis, #lecture, #course, #tutorial In this video, we discuss padding. When you encrypt a ciphertext using a block cipher, the last block may be of a different size than the cipher's block size. In this case, we pad. Here, we discuss different padding modes in detail as well as have a look at these in CrypTool 2. Padding modes we discuss: - “None” - 0-Padding - 1-0-Padding - ANSI X9.23 Padding - ISO 10126 Padding - PKCS#7 Padding If you are interested in learning the fundaments of cryptology, let me invite you to have a look at our video series about the basics of cryptology, also for beginners: https://youtu.be/jbumW7Ym03o You can download the latest version of CrypTool 2 from here: https://www.cryptool.org/en/ct2/downloads Visit my blog: https://www.kopaldev.de Like what I do 😄?
