Something like this: Cipher aes = Cipher. GetInstance("AES/ECB/PKCS5Padding"); SecretKeySpec key = new SecretKeySpec(yourKeyBytes, "AES"); aes. Init(Cipher.
DECRYPT_MODE, key); byte cleartext = aes. Update(ciphertext, 0, ciphertext. Length).
Make sure you're doing the padding etc in the right order first: pad then encrypt, decrypt then unpad. Check the transmitted data length and make sure it's a multiple of blocksize. Make sure blocksize is consistent in all the calls.
Make sure your crypto provider settings are exactly matching.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
