Part 4/8:
To illustrate vulnerabilities in encryption protocols, Dave recounts the history of the Data Encryption Standard (DES). Once deemed a robust encryption method with 56-bit keys, DES was eventually outpaced by advancements in computing power. The landmark challenges posed by initiatives like the Electronic Frontier Foundation's Deep Crack demonstrated the feasibility of brute-forcing DES keys in merely days, raising alarms that fundamentally altered the landscape of cryptography.
