pysqlitecrypto-rsa 0.1.2

A package for RSA encryption and decryption using SQLite storage.

Pysqlitecrypto-RSA

Pysqlitecrypto-RSA is a Python package that provides functionalities for RSA key generation, encryption, and decryption using SQLite storage.

Installation

To install Pysqlitecrypto-RSA, you can use pip:

pip install pysqlitecrypto-rsa

Make sure you have Python 3.x installed.

Usage

You can use Pysqlitecrypto-RSA in your Python projects by importing the necessary functions:

import os
from pathlib import Path

# Import functions from the libraries
from pysqlitecrypto_rsa import generate_keys, encrypt_message, decrypt_message

# Define the home directory and the keychain directory
home_dir = str(Path.home())
keychain_dir = os.path.join(home_dir, ".keychain")

# Define the key size for RSA keys
key_size = 1024

# Generate RSA keys with a specified key size
if os.path.exists(keychain_dir):
    # Check if the keychain directory already exists
    choice = input(".keychain folder already exists. Do you want to generate new keys? (y/n): ")
   
    if choice.lower() == 'y': 
        # If the user chooses to generate new keys, remove the existing keychain
        # directory and create a new one with new keys
        generate_keys(key_size, True, keychain_dir)
else:
    # If the keychain directory doesn't exist, create it and generate new keys
    message = generate_keys(key_size, False, keychain_dir)
    print(message)

# Encrypt a message
encrypted_message = encrypt_message("Your message here")
print("Encrypted message:", encrypted_message)

# Decrypt the encrypted message
decrypted_message = decrypt_message(encrypted_message)
print("Decrypted message:", decrypted_message)

Note:

• The generate_keys function requires the key size to be passed as an argument. For example, generate_keys(1024) generates RSA keys with a key size of 1024 bits.
• The generate_keys function creates a folder called '.keychain' in the home directory, and inside it, a keys.db file is created to store the RSA keys.
