Program Code – Python for Deciphering Advanced Encryption Algorithms

import base64
from Crypto.Cipher import AES
from Crypto.Util.Padding import pad, unpad
from Crypto.Random import get_random_bytes

class AdvancedEncryptionStandard:
    def __init__(self, key):
        self.key = key

    def encrypt(self, plaintext):
        '''Encrypt plaintext using AES (CBC mode) with PKCS7 padding.'''
        cipher =, AES.MODE_CBC)
        ct_bytes = cipher.encrypt(pad(plaintext.encode(), AES.block_size))
        iv = cipher.iv
        result = base64.b64encode(iv + ct_bytes).decode()
        return result

    def decrypt(self, ciphertext):
        '''Decrypt ciphertext using AES (CBC mode) with PKCS7 padding.'''
        ct_decoded = base64.b64decode(ciphertext)
        iv = ct_decoded[:AES.block_size]
        ct = ct_decoded[AES.block_size:]
        cipher =, AES.MODE_CBC, iv)
        pt = unpad(cipher.decrypt(ct), AES.block_size).decode()
        return pt

# Initialization and usage
key = get_random_bytes(16)  # AES key must be either 16, 24, or 32 bytes long
aes_cipher = AdvancedEncryptionStandard(key)

# Encrypt
plaintext = 'Secret Message to Encrypt'
ciphertext = aes_cipher.encrypt(plaintext)
print(f'Ciphertext: {ciphertext}')

# Decrypt
decrypted_message = aes_cipher.decrypt(ciphertext)
print(f'Decrypted Message: {decrypted_message}')

Code Output:

  • The Ciphertext will contain a base64 encoded string that represents the encrypted version of the plaintext. It will look something like ‘6yJ5jdJeFxvHy…’ but will vary in each execution since the initialization vector (IV) and the key are random.
  • The Decrypted Message will output ‘Secret Message to Encrypt,’ demonstrating that the original message has been recovered from the ciphertext.

Code Explanation:

Here’s a dive into the cerebral abyss of the program’s logic:

  1. Import the required modules: The script utilizes base64 for encoding and decoding, Crypto.Cipher.AES for the encryption and decryption process, Crypto.Util.Padding for padding the message to be a multiple of the block size, and Crypto.Random to generate a random key.
  2. Create an AdvancedEncryptionStandard class: This masterclass of cryptography has a constructor that takes a key and functions for both encryption and decryption of messages.
  3. In the encrypt method: The real magic! It initiates a cipher using the given key and AES in CBC mode. Padding the plaintext to the AES block size follows, leading to encrypting the message. It splices together the initialization vector and the encrypted message, then, SHAZAM! It serves up a base64 encoded string.
  4. In decrypt function: A reverse spell that first decodes the base64 string, retrieves the IV, and decrypts the ciphertext. After undoing the ‘encrypt-o-patent,’ it unpads the plaintext to its original form, ‘Abracadabra!’ The message returns to its initial state.
  5. Initialization and usage: A key is generated using get_random_bytes to ensure it’s as unpredictable as a greased lightning bolt. An instance of the class is created with this key.
  6. Encrypt a plaintext message: This demo text is put through the ‘encrypt’ method, coming out the other side as an enigma wrapped in a cipher.
  7. Decrypt the ciphertext: The gibberish is pushed through the ‘decrypt’ method, reemerging as the original plaintext, proving the sorcery worked properly.

The story here is one of transformation – plaintext to ciphertext and back again, like a digital Phoenix rising from binary ashes.
