Mastering AES Encryption: Secure Your Data with Python
AES (Advanced Encryption Standard) is a symmetric key algorithm that converts plaintext into ciphertext. Its basic formula is:
[ C = E_K(P) ]
Where (P) is plaintext, (E_K) is the encryption function using key (K), and (C) is ciphertext. AES supports 128, 192, and 256-bit keys for varying security levels.
Python Implementation Example
from Crypto.Cipher import AES
from Crypto.Util.Padding import pad, unpad
key = b'Sixteen byte key'
cipher = AES.new(key, AES.MODE_CBC)
plaintext = b'Secret message'
ciphertext = cipher.encrypt(pad(plaintext, AES.block_size))
print('Encrypted:', ciphertext)
# Decrypt
decipher = AES.new(key, AES.MODE_CBC, cipher.iv)
decrypted = unpad(decipher.decrypt(ciphertext), AES.block_size)
print('Decrypted:', decrypted)
