📌 Introduction to Encryption

Encryption transforms readable data into an unreadable format to protect confidentiality. Whether you're securing messages, files, or databases, understanding encryption is vital in today's digital age.

🧩 Key Encryption Concepts

  • Symmetric Encryption: Uses a single key for encryption and decryption (e.g., AES).

  • Asymmetric Encryption: Relies on a public/private key pair (e.g., RSA).

  • Hash Functions: Convert data into a fixed-size string (e.g., SHA-256).

🛠️ Practical Steps to Implement Encryption

  1. Generate Keys
    Use tools like OpenSSL or cryptographic libraries to create secure keys.
  2. Encrypt Data
    Apply symmetric algorithms for bulk data or asymmetric methods for key exchange.
  3. Decrypt Data
    Ensure proper key management to restore encrypted data.

🧠 Security Best Practices

  • Regularly update encryption algorithms to address vulnerabilities.
  • Combine encryption with authentication (e.g., HMAC).
  • Store keys securely using hardware modules or encrypted key stores.
