Encrypt and Decrypt Files using Python
Encrypting and decrypting files with Python involves securing data with a secret code (encryption) and revealing it back (decryption) using specialized tools, ensuring privacy and data integrity in digital communication.
We’ll use a special library called cryptography to make a file secret. This library uses a method where we use the same secret key to hide and reveal the file. The cryptography library has easy-to-use tools to make the key, hide text, and show hidden text. It’s called the fernet module. It makes sure that only people with the secret key can unlock the hidden information.
Encryption:-
Encryption is like putting your message or file into a secret box . We use a special key, like a secret password, to lock the box. Nobody can understand what’s inside the box without the key.
Decryption:-
Decryption is using a key to unlock a secret code. With the correct key, we open the code, revealing the original message or file. It’s like opening a locked box to see what’s inside, turning the secret back into readable text.
Project Working of How To Encrypt And Decrypt A File In Python:-
Encryption and Decryption of file using python programming language and graphical user interface developed using tkinter (python library). user have to run python script and home page will open, it is a type of desktop software and there is three buttons; Encryption, Decryption and Exit Buttons. once user click on encryption button then new window will open and user can browse any file and click on key generation button and it will generate private key and then click on encrypt button. so this file can decrypt using decryption process, were user have to select cipher file and enter that particular key and select decrypt option then it will decrypt that encrypted file.
