- - - - Definition: Same key for encryption and decryption.
      - Examples
        
        AES (Advanced Encryption Standard)
        
        DES (Data Encryption Standard)
        
        Triple DES
      - Advantages
        
        Fast and efficient.
      - Limitations
        
        Key distribution problem.
    - - Definition: Uses a pair of keys—public and private.
      - Examples
        
        RSA (Rivest–Shamir–Adleman)
        
        ECC (Elliptic Curve Cryptography)
        
        Diffie-Hellman
      - Advantages
        
        Secure key exchange.
      - Limitations
        
        Slower compared to symmetric encryption.
    - - Definition: One-way encryption without a key.
      - Examples
        
        SHA-256 (Secure Hash Algorithm)
        
        MD5 (Message Digest)
        
        Blake2
      - Applications
        
        Password storage.
        
        Data integrity checks.
  - - - Ensuring data is accessible only to authorized users.
    - - Verifying that data hasn’t been altered.
    - - Confirming the identity of the communicating parties.
    - - Preventing denial of actions.
  - - - Protecting sensitive information in databases.
    - - Securing emails (PGP).
      - Securing VoIP communications.
