Master Cryptography: Understanding the Feistel Scheme in Symmetric Encryption 🔐

Feistel networks are often used in symmetric cryptography applications, like DES. Learn to encrypt and decrypt with these ciphers in Wolfram Language. Compare their structure and strengths to SPN ciphers in the final lesson of this section. The next section will cover public-key cryptography.

In the full course, you will learn how and when to use hash functions and symmetric and asymmetric ciphers, as well as the basics of information security through instruction on the fundamentals and real-life applications of each concept.
