Encryption is a fundamental pillar of cybersecurity, ensuring data confidentiality, integrity, and authenticity. Here's a concise overview of its core concepts:

🔑 What is Encryption?

Encryption transforms readable data (plaintext) into unreadable ciphertext using algorithms and keys. This process protects information from unauthorized access, even if intercepted.

  • Purpose: Secure communication, data storage, and identity verification.
  • Key Types:
    • Symmetric Key: Uses a single key for encryption and decryption (e.g., AES).
    • Asymmetric Key: Uses a public-private key pair (e.g., RSA).
    • Hash Functions: One-way transformations (e.g., SHA-256).

🛡️ Common Encryption Applications

  1. Secure Messaging: End-to-end encryption (e.g., WhatsApp).
  2. Data Protection: Encrypting files or databases.
  3. Authentication: Verifying user identities via encrypted credentials.
  4. SSL/TLS: Securing web traffic (e.g., HTTPS connections).
