Cryptizia 0.2.1

A Python library for various cipher techniques including the Caesar cipher and Playfair cipher examples.

Cryptizia

Cryptizia is a Python library for various cipher techniques including the Caesar cipher.

Installation

You can install the library using pip:

pip install cryptizia

How to use in Code

Caeser Cipher

from cryptizia import CaesarCipherExample

CaesarCipherExample()

Customization

You can customize the 'shift' and 'plaintext' directly in the constructor if you want different values:

# Example with custom shift and plaintext
cipher = CaesarCipherExample(shift=5, plaintext="WORLD")

You can encrypt and decrypt whole file using Caeser Cipher class

from CaeserCipher import CaesarCipher

# Example usage with a file
def encrypt_file(input_file, output_file, shift):
    cipher = CaesarCipher()
    
    # Read the content of the input file
    with open(input_file, 'r') as file:
        file_content = file.read()
    
    # Encrypt the content
    encrypted_content = cipher.caesar_encrypt(file_content, shift)
    
    # Write the encrypted content to the output file
    with open(output_file, 'w') as file:
        file.write(encrypted_content)

def decrypt_file(input_file, output_file, shift):
    cipher = CaesarCipher()
    
    # Read the content of the input file
    with open(input_file, 'r') as file:
        file_content = file.read()
    
    # Decrypt the content
    decrypted_content = cipher.caesar_decrypt(file_content, shift)
    
    # Write the decrypted content to the output file
    with open(output_file, 'w') as file:
        file.write(decrypted_content)

# Example: Encrypting and decrypting a file
encrypt_file('example.txt', 'encrypted.txt', 3)  # Encrypt 'example.txt' with a shift of 3 and save it as 'encrypted.txt'
decrypt_file('encrypted.txt', 'decrypted.txt', 3)  # Decrypt 'encrypted.txt' with a shift of 3 and save it as 'decrypted.txt'
