 This script creates an instance of `Pyfhel`, generates a public and secret key with `keyGen()`, encrypts two integers using `encryptInt()`, adds and multiplies them, then decrypts the results using `decryptInt()`. The decrypted results should be equal to the results of adding and multiplying the original, unencrypted numbers.
 
 Remember that this is a simplified example. In a real-world scenario, key management and ensuring the security of the encryption and decryption operations are crucial and more complex. Furthermore, full homomorphic encryption is a computationally intensive task and may not be suitable for all types of data or applications.
