Basics of Cryptology – Part 5 (Modern Cryptography – Stream Ciphers – RC4)
#cryptology, #cryptography, #cryptanalysis, #lecture, #course, #tutorial In this video, we show the basics of cryptology (cryptology = cryptography and cryptanalysis). This particular video shows in detail how the modern stream cipher RC4 works. First, we discuss in detail the internal workings of RC4 and give a brief overview of its invention. Then, we show a visualization of RC4 in JCrypTool (10:04). Finally, we use CT2 (from 13:04) to encrypt and decrypt text using RC4. Here, we also show what happens, if you change a byte in the plaintext, ciphertext, or in the key.
