Why Choosing the Right Cryptography Matters for Cybersecurity 🔐

Cryptography is at the heart of cybersecurity — it protects data, communications, and trust.
In this video, we break down Section 1.4 of CompTIA Security+ (SY0-701): Cryptographic Solutions. You’ll learn why using the right cryptography matters, how it’s applied, and what tools support it.

We cover:

Public Key Infrastructure (PKI) – public/private keys, key escrow

Encryption methods – symmetric, asymmetric, full-disk, file, database, transport/communication

Tools – TPM, HSM, key management systems, secure enclaves

Obfuscation – steganography, tokenization, data masking

Cryptographic techniques – hashing, salting, digital signatures, key stretching

Emerging tech – blockchain, open public ledgers

Certificates – authorities, CRLs, OCSP, CSR, wildcard, root of trust

This section helps you master encryption and trust models, both for the exam and real-world cybersecurity.
