Fixing up the AESEncryptor

A follow on to my previous posts about using the Java Cryptography stuff to perform simple encryption. It turns out I was using a proprietary class from Sun for the Base64 encoding/decoding.

I got rid of the imports for the proprietary classes:

import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;

And used the Base64 class from org.apache.commons.codec.

This only required a few minor changes to the decode/encode calls.

AES and Java: Part the Third

So, in review, I needed to be able to encrypt a string using AES.

• I started with a simple test to see if I could get the original string back after encrypting it.
• The next step was to actually try hooking up the Java Cryptography classes to do the heavy lifting.
• In this installment I'll clean up my current solution and extend it just a bit to be more generally useful.

JCE Exploration Part 2

As I explained in my prior post I'm trying to figure out how to use the Java Cryptography classes to encrypt a string using AES.

I have a little test that passes but doesn't actually do any encryption. How shall I proceed?
