AES input and output : <p>I want an implementation of AES that takes as parameters two String inputs (plaintext, key) and outputs the encrypted String ciphertext. I have search all over the Internet but I haven't found. I have found AES that has byte[] input and outputs String and the other way round. Is it already implemented or I have to play aroundwith Java and create some methods that will finally do the job? 
Thank you!</p>
