Summary
Ayomide Oluwaga introduced Domain 1.4 focusing on cryptographic solutions for cybersecurity, covering PKI, encryption types, data integrity, and blockchain, in preparation for the CompTIA Security+ exam. EL N and Ikedi Emmanuel provided feedback on the previous quiz, noting its improved relevance to the exam format but also pointing out questions on unaddressed topics. Ayomide Oluwaga conducted a practical demonstration of asymmetric encryption and key generation, illustrating how public and private keys work, and discussed real-world applications and cryptographic tools like TPMs and HSMs, as well as data obfuscation techniques such as steganography, tokenization, and data masking.
