Encryption is a fundamental technique in cybersecurity used to protect data confidentiality and integrity. By converting plaintext into ciphertext, it ensures only authorized parties can access sensitive information.

Key Concepts 🔐

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

    AES Encryption

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

    RSA Encryption

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

    SHA-256 Algorithm

Common Use Cases 🌐

  • Data Transmission
    Secures communication over networks (e.g., HTTPS).
  • Data Storage
    Protects sensitive information in databases.
  • Identity Verification
    Ensures authenticity through digital signatures.
