Today we'll use the XTEA encryption/decryption code we loaded last time. It's a simple tool, and easy to use for small projects without terribly solid encryption needs. To get started, just use code like this: The first 16 characters are your key:

cipher := 'this is my string for encryption/decryption' 
	xteaEncryptWithKey: 'my encryption key'.

That encrypts; you can inspect the cipher to see the binary data. Next, use the same key to decrypt it:

plain := cipher xteaDecryptWithKey: 'my encryption key' 'this is my string for encryption/decryption'

That's it - for simple use cases, that's all you need.

Welcome to episode 36 of "Thu'umcast" - a podcast where Michael Lucas-Smith, Scott Dirk, Austin Haley, Makahlua and I document our trials and tribulations in Elder Scrolls V: Skyrim Michael, Scott, Maki, and James are back to talk about Dragon Born now that it's out for PC. We all like this expansion a lot - and Maki helps tie in the old Morrowind lore to what we're seeing in Solstheim. We went long, so this is split into two parts. Episode 37 will be out soon.. If you liked our work on That Podcast, you'll probably like this. We intend to stay with the same idea - a gameplay podcast. If you don't want spoilers, don't listen - we are going to be talking about how we play the game, and what we ran across as we played.

Today we'll look at a way you can break encapsulation in Smalltalk - useful for some low level tasks (interfacing with databases, for instance) - but dangerous in general. Still, it's useful to know what you can accomplish, so long as you are also aware of the dangers. Consider this class:

Object subclass: #Person
    classInstanceVariableNames: 'nextId '
    instanceVariableNames: 'id first last '
    classVariableNames: ''
    poolDictionaries: ''

Now consider this code:

person := Person new.
person first: 'James'.
person last: 'Robertson'.


person instVarAt: 1

Execute that, and you should get back the value in 'id' = the first instance variable. Again this is not something you want to make use of on a normal basis. It can be useful when debugging (say you have a class without accessing methods), or when creating accessing frameworks for external data. Similarly:

person instVarAt: 1 put: 0.
