This project is a Python application that allows users to securely encrypt and decrypt their files. The program encrypts files using the XChaCha20-Poly1305 encryption algorithm and derives a 256-bit long key with the argon2 KDF algorithm. It also offers SHA-256 hash calculation to verify the integrity of the files.
- File Encryption: Encrypts the user's selected file and saves the encrypted file with the .enc extension.
- File Decryption: Decrypts the encrypted file selected by the user.
- File Integrity Verification: Calculates and compares SHA-256 hash values of files.
- Chunk Size Setting: Ability to set the chunk size in MB to be used during operations.
- Random Key Generation: Allows the user to generate a random key of a specific length.
- Send message to producer: Allows you to provide feedback to the producer.
The following Python libraries are needed for this program to work:
- nacl: PyNaCl library, required for the XChaCha20-Poly1305 encryption algorithm.
- tkinter: Required for GUI components and file selection operations.
- colorama: Used for color output in the terminal.
- hashlib: Required for SHA-256 hash calculation.
- argon2: Required for argon2 KDF algorithm.
- msvcrt: Used for keyboard input control (only works on Windows systems). Also, Python 3.8 or higher must be installed.
You can use the following commands to install the required libraries:
pip install pynacl, pip install colorama, pip install argon2-cffi ...
The program can be run through the terminal. When run, it offers the user several options:
-
Encrypt: Selects the file to be encrypted and encrypts it.
-
Decrypt: Decrypts the encrypted file.
-
Set Chunk Size: Sets the chunk size to be used for encryption and decryption.
-
File Integrity Verify: Calculates and compares SHA-256 hash values of files.
-
How It Works: Explains how the program works.
-
Producer: Provides information about the producer of the program.
-
Send message to producer: Allows you to leave feedback to the producer.
-
Exit: Exits the program.
-
Key Generation: The program requests an encryption key from the user. The user can generate a random key of a certain length by entering the /generate key[x] command. For example, the command /generatekey16 generates a key 16 characters long.
-
Chunk Size Setting: The user can set the chunk size in MB. By default, the chunk size is set to 2 MB for encryption and decryption operations.
-
File Integrity Verification: To verify file integrity, the user can calculate the SHA-256 hash value of the file and then compare this value. This feature is useful for checking if files have been modified.
