WebWith AES, or any serious encryption algorithm, even if you have the encrypted data (the ciphertext) and the original message (the plaintext), you are no closer to finding the encryption key. This is known as a known-plaintext attack, and AES is resistant to known-plaintext attacks as it should be. Or you might have meant HMAC -SHA-256.
