Part1: Writing a program that uses AES-128 to decrypt a message using the ciphertext (ciphertext.dat) and secret key (key.dat) for testing.

Part2: Using "brute force" to decrypt an encrypted message, where only having the first 96-bits of the 128-bit secret key (last 4 bytes of the secret key are missing!) and the original message starts with the word "Salam". Using the ciphertext (ciphertext2.dat) and partial key (partial-key.dat) for testing.
