Encryption/Decryption program - Python Language

Encryption/decryption program: A program for encryption and decryption can be created using a library such as Pycrypto or cryptography to encrypt and decrypt data using a variety of algorithms. 

Here is a sample code for Encryption/Decryption program:

This code uses the cryptography library to encrypt and decrypt data using the Fernet algorithm. The Fernet.generate_key() function generates a key to be used by the Fernet cipher. The encrypt_data(data) function encrypts the given data by encoding it to bytes and then encrypting it using the cipher. The decrypt_data(encrypted_data) function decrypts the given data by decrypting it using the cipher and then decoding it to a string.

Good Luck!
