     9  These methods are often used to ensure security and protect data in the "Smart Home" system.
    10  
    11  1. `Encrypt(val)`: This method is used for data encryption. It takes a value (`val`) as input and encrypts it, typically to ensure the security of confidential information or data.
    12  
    13  2. `Decrypt(val)`: This method is used for data decryption. It takes the encrypted value (`val`) as input and decrypts it, returning it to its original state.
    14  
    15  Example of using the `Encrypt` and `Decrypt` methods in the "Smart Home" system in the JavaScript programming language:
    16  
    17  ```javascript
    18  // Data Encryption
    19  const originalData = "Secret Information"; // Original data
    20  const encryptedData = Encrypt(originalData); // Encryption
    21  
    22  console.log("Original Data:", originalData);
    23  console.log("Encrypted Data:", encryptedData);
    24  
    25  // Data Decryption
    26  const decryptedData = Decrypt(encryptedData); // Decryption
    27  
    28  console.log("Decrypted Data:", decryptedData);
    29  ```
    30  
    31  In this example, we first encrypt the string "Secret Information" using the `Encrypt` method. Then we decrypt the encrypted data using the `Decrypt` method. After decryption, we get the original data back.
