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?

A little excursion into JCE

I had an occasion to explore a bit of Java that I've never dealt with before: the Java Cryptography Extensions (as of Java 1.4 these are part of the Java distribution). The problem at hand required being able to encrypt a string using the Rijndael algorithm (AES).

We had eight open-sourcers tonight. The largest contingent was Greg Heartsfield and his friends from Bell--Nick and first-timer Mike. We had two other newcomers--Kevin and Engin.

Starting off on the write foot...

...and by that I mean writing tests....

It has been a few frustrating sessions at Dallas Geek Night.

I've looked at a couple of technologies for writing iOS apps (even though I don't yet have an iPhone or iPad).

• mobl is like a DSL where you can declaratively layout screens and controls and will run in a webkit based browser.
• MonoTouch is a commercial plugin for MonoDevelop that allows you to write iOS apps in C#

I've also looked at partychapp.

So what is my frustration? Tests or the lack thereof.
When I start to work on a project I want to be able to quickly start writing unit tests.

We had 7 developers at the Addison ThoughtWorks office. Several worked on different aspects of StoryNavigator.

Stumbling around Google collections

I came across a situation in some code I need to modify where maps were being 'filtered' to create tailored data for different situations. I couldn't come up with the solution I wanted in the moment so I cobbled up an example to see what might work.
