(1)Key generation.
(2)Encryption.
(3)Decryption.
Hint:
(i)For key generation, input the original key and generate round keys.
(ii)For encryption, input a sentence, convert it to ASCII codes, divide it into blocks, encrypt each block with the round keys, and output the ciphertext of the sentence.
(iii)For decryption, input the ciphertext (cut/paste), divide it into blocks, decrypt each block with the round keys, convert the plaintext to the sentence on the basis of ASCII codes
Good evening,
As you can see in my reviews, I am an experienced Java programmer and computer scientist and will happily make the implementation for you.
I am based in London so communication won't pose any problems :)
Best,
Przemysław

Hi, my name is Raul and I am a computer engineer from Brazil. I already implemented AES in C language.
Is it needs to have an original code? If don't I think that I can deliver in 12 hours.
I have a lot of experience with Java and i would be very interested on implementing your task. If you are interested too contact with me for more details.
