Why Proper Encryption Matters

  • 🔒 256-bit AES military-grade protection
  • 📈 95% of data breaches involve weak encryption
  • ⚖️ GDPR/HIPAA compliance requirements
Did You Know?

Base64 increases data size by 33%

Encryption Methods Comparison

Method Security Level Use Case Speed
AES-256 Military Sensitive data Fast
RSA-4096 Bank-grade SSL/TLS Slow
SHA-256 One-way hash Passwords Instant

Security Best Practices

🔑 Key Management
  • Use hardware security modules
  • Rotate keys quarterly
🚨 OWASP Recommendations
  • Validate input formats
  • Prevent padding oracle attacks
📜 Compliance
  • GDPR Article 32
  • PCI DSS 3.2.1

Real-World Applications

🔐 Password Storage
SHA-256(salt + password)

Always salt before hashing

📨 Secure Messaging
AES-256-GCM encryption

With HMAC authentication

💳 Payment Processing
PCI DSS compliant tokens

Tokenization vs encryption

Encryption Implementation Checklist

Critical: Never store encryption keys in code!
  1. Choose FIPS 140-2 validated algorithms
  2. Use TLS 1.3 for data in transit
  3. Implement HSM for key storage
  4. Regular penetration testing
  5. Audit third-party crypto libraries

FAQ: Text Cryptography

Encoding (Base64/Hex) is for data transfer, encryption (AES) provides security. Base64 != Encryption

Article 32 mandates encryption of personal data using state-of-the-art methods like AES-256 with proper key management.
