pyfilecrypto 1.0.3

A module for file encryption and decryption

pyfilecrypto Documentation

Overview

The pyfilecrypto module provides functionality for file encryption, decryption, and zip compression with password protection in Python. It leverages cryptography.fernet for file encryption and pyzipper for handling zip files with AES encryption.

Import

from pyfilecrypto.crypto import *

Classes

ACrypto

Methods:

• genKey(filename): Generates a new encryption key and saves it to the specified file.

ACrypto.genKey(filename)

• loadKey(filename): Loads an encryption key from the specified file.

ACrypto.loadKey(filename)

• encryptFile(original_filename, save_as, keyfile): Encrypts a file using the specified encryption key file and saves the encrypted data to another file.

ACrypto.encryptFile(original_filename, save_as, keyfile)

*decryptFile(filename, save_as, keyfile): Decrypts an encrypted file using the specified encryption key file and saves the decrypted data to another file.

ACrypto.decryptFile(filename, save_as, keyfile)

BCrypto

Methods:

• Encrypt(filename): Encrypts a file with multiple encryption keys ("alpha", "bravo", "charlie").

BCrypto.Encrypt(filename)

• Decrypt(filename): Decrypts a file that was encrypted with multiple keys ("charlie", "bravo", "alpha").

BCrypto.Decrypt(filename)

• crypt(filename, method): Encrypts or decrypts a file based on the specified method ("encrypt" or "decrypt").

BCrypto.crypt(filename, method)

Crypto

Methods:

• crypt(filename, method, password): Encrypts or decrypts a file with password-protected zip archive support.

Crypto.crypt(filename, method, password)

Usage

Method: 1

Generate Encryption Key and Encrypt File

from pyfilecrypto.crypto import ACrypto
ACrypto.encryptFile("test.txt", "test.enc", "my_secret.key")

Use key and Decrypt File

from pyfilecrypto.crypto import ACrypto
ACrypto.decryptFile("test.enc", "test.txt", "my_secret.key")

Method: 2

Generate Encryption Key and Encrypt File

from pyfilecrypto.crypto import BCrypto
BCrypto.Encrypt(filename = "test.txt")

Use keys and Decrypt file

from pyfilecrypto.crypto import BCrypto
BCrypto.Decrypt(filename = "test.txt")

Method: 3

Generate Encryption key and Encrypt File

from pyfilecrypto.crypto import BCrypto
BCrypto.crypt(filename = "test.txt", method = "encrypt")

Decrypt file using keys

from pyfilecrypto.crypto import BCrypto
BCrypto.crypt(filename = "test.txt", method = "decrypt")

Method: 4

Encrypt and Decrypt file with keys

from pyfilecrypto.crypto import Crypto
Crypto.crypt(filename = "test.txt", method = "encrypt", password = "password")
Crypto.crypt(filename = "test.txt", method = "decrypt", password = "password")
