Create Your Own File Encryption and Decryption Tool with Python. “Encryption is the most effective way to achieve data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt it.” — Bruce Schneier Are you seeking a rewarding and interesting programming project to dive into? If so, you might want to attempt making a file encryption and decryption application yourself! This is not only an excellent method for discovering more about data security and encryption, but it's also a useful tool you can use to protect your private documents. We'll walk you through the steps of creating a file encryptor and decryptor in python in this video. Even if you are unfamiliar with programming, you will be capable of adhering along since we will break down every code line and describe what it does. You'll have full-functioning encryption as well as a decryption tool by the end of this video that can be used to secure your documents from prying eyes. then let's get going! Download the Source Code for File Encryption and Decryption Tool. Please download the source code for the Project using the link: https://github.com/Akkmr111/Create-Yo... Getting Started The requirement for this Python project can be installed using commands: 1. Cryptography – pip install cryptography Generating a Key To encrypt and decrypt files, we need to generate a key that will be used to encrypt and decrypt the data. To generate the key, we will use the Fernet class from the cryptography package. The generate_key() function generates a key and saves it to a file named secret.key. We are using the with statement to ensure that the file is properly closed after the key is written. Loading the Key Now that we have generated the key, we need to load it to use it for encryption and decryption. The load_key() function opens the secret.key file and returns its contents. Encrypting the File The encrypt() function takes two parameters: the filename of the file to encrypt and the key used to encrypt it. First, we create a Fernet object with the key. Then, we open the file in binary mode and read its contents. We then use the encrypt() method of the Fernet object to encrypt the file data. Finally, we write the encrypted data back to the same file. Decrypting a File To decrypt a file, we need to load the key from the secret.key file and use it to decrypt the contents of the encrypted file. The decrypt() function takes two arguments: the filename of the encrypted file and the key to decrypt it. First, we create a Fernet object using the key. Then, we open the encrypted file in binary mode and read its contents. We then use the decrypt() method of the Fernet object to decrypt the contents of the file. If the key is invalid or the file has been tampered with, we catch the Invalid Token exception and print an error message. Otherwise, we write the decrypted contents to the same file. Putting it All Together Now that we have implemented the generate_key(), load_key(), encrypt(), and decrypt() functions, we can use them to encrypt and decrypt files. We first ask the user whether they want to encrypt or decrypt a file, and then prompt them for the filename. We then call the appropriate function based on the user's choice.
