Xipher

Xipher is a simple GUI for encrypting/decrypting files using PyQt5 and AES. User can select a file, enter a password and encrypt or decrypt it. The encryption/decryption uses a password-based key generated using PBKDF2. Good for demonstration, but use a vetted library in real-world scenarios. File Crypto GUI This script is a python script that provides a Graphical User Interface (GUI) for encrypting and decrypting a file.

Requirements

python3

PyQt5

Crypto

struct

Usage

Run the script by python3 filecrypto.py In the GUI, you'll be prompted to enter a password, browse for a file and select whether to encrypt or decrypt the file. After the selection the process of encryption or decryption will take place.

Dependencies

PBKDF2 is missing in the crypto library, you should add it. import struct is also missing in the script.

Note

The encryption is using AES CBC encryption mode and the key is created using PBKDF2. The key is derived from the password entered by the user. The file encryption and decryption functions have a chunksize parameter that can be adjusted for optimal performance. This script is for educational purposes only, always make sure to use industry-standard encryption and authentication methods when working with sensitive data.

Limitations

This script is not suitable for large files, as the encryption and decryption process is done in memory. There is no exception handling in case of wrong file path, missing dependencies or wrong password. There is no authentication mechanism to check the access level of the user. There is no limit of password length.

Changelog

PBKDF2 is added. struct import is added.

Future Work

Add exception handling mechanism. Add authentication mechanism. Add limit of password length. Make it suitable for large files encryption and decryption.
