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.
