I need to know how to create an AES and using it to encrypt and decrypt a file in java.

回答1:

Try using a CipherOutputStream and passing in a FileOutputStream. See http://www.java2s.com/Tutorial/Java/0490__Security/UsingCipherOutputStream.htm for a quick example, just use Cipher.getInstance("AES/CBC/PKCS5Padding") instead.
