طلب كود تشفير Aes-128 بالجافا؟

السؤال الاول:

write a java program that uses AES 128 to decrypt a cipher text. Your

program should have a GUI which accepts cipher text file & decryption key file from the user and displays the resulting plaintext and the decryption time

السؤال الثاني:

You will try to run a brute force attack on a cipher text encrypted with AES-128. You are given a cipher

text and part of the key (104 bits). Write a program that should run a brute force attack to figure out the

remaining 24 bits. You should know that you found the correct key if the decrypted text starts with

“Stocks”. Your program should display:

· The resulting plain text

The time it took to crack the key.

· The full key in hexadecimal.
