Section 1.4 – Explain the importance of using appropriate cryptographic solutions

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. #SecurityPlus #CompTIASecurityPlus #Cryptography #Encryption #PKI #CybersecurityFundamentals #SY0701 #SecurityExamPrep
