🔒 Encryption Fundamentals

Secure your digital world with modern encryption technology. Learn the core principles of data protection.

What is Encryption?

Encryption converts readable data (plaintext) into an unreadable form (ciphertext) using algorithms. Modern encryption protects sensitive information across networks, from banking transactions to personal messages.

  • ✅ Prevents unauthorized data access
  • 🌐 Critical for online security protocols (TLS, HTTPS)
  • ⚙️ Used in blockchain, secure messaging, and cloud storage

Symmetric Encryption

Uses a single key for both encryption and decryption. Fast and efficient for large data sets.

AES-256 - Industry standard for symmetric encryption

Asymmetric Encryption

Uses public/private key pairs. Enhances security for key exchange and digital signatures.

RSA - Widely used for secure communications
