Encryption technology is a cornerstone of modern cybersecurity, protecting data integrity and confidentiality. Here's a concise guide:
Key Concepts
- Symmetric Encryption: Uses a single key for encryption and decryption (e.g., AES_algorithm)
- Asymmetric Encryption: Relies on public/private key pairs (e.g., RSA_algorithm)
- Hash Functions: Convert data into fixed-size hashes (e.g., SHA_hash)
Common Use Cases
- Data Transmission (e.g., TLS_protocol)
- Secure Storage (e.g., AES_encryption)
- Identity Verification (e.g., HMAC_hash)
Best Practices
⚠️ Always:
- Use strong algorithms
- Implement key management
- Enable multi-factor authentication
