Cryptography for Everybody

@UC8_FqvQWJfZYxcSoEJ5ob-Q - 20.8K subscribers

Hello and welcome to my cryptology channel! I am Nils, a cryptology maniac and specialist. Currently, I lead the development of the open-source software CrypTool 2. In my professional life, I work as a professor at the Hochschule Niederrhein (University of Applied Sciences) and the Cyber Campus NRW in the realm of IT security. Previously, I worked as a post-doc at the University of Siegen in the DECRYPT project, where we collected, analyzed, and decrypted historical ciphertexts from around the world. On this YouTube channel, you learn about cryptology = cryptography (making codes/ciphers) and cryptanalysis (breaking codes/ciphers). From the Zodiac Killer's ciphers to the famous Enigma. From modern AES to RSA. If you are interested in secret codes, subscribe to this channel!
