Squeak People diary for kjw http://people.squeakfoundation.org/person/kjw/ Thu, 05 Aug 2004 02:29:20 -0700 http://people.squeakfoundation.org/person/kjw/diary.html?start=1 <b>squeakfan.com</b> <p> <p>A very kind friend gave me an early birthday present, and registered squeakfan.com for me. I have something of a vision for the web end of this -- a place where information that's too newbielicious for the wiki and other official Squeak places can go. <p> <p>A good example would be me catching myself using shared pools to assign numeric constants to states for a very simple state machine -- and realizing that the best way to go would probably be to use symbols, which are guaranteed to be unique (rather than constants, which I might accidentally assign the same values to). <p> <p>It wouldn't be so bad if I wasn't a fairly seasoned Lisper and Schemer. Talk about embarrassing! <p> <p>But there you have it -- a place for all of the "really-obvious-but-might-still-need-to-be-reminded" stuff to go. <p> <b>SHA, AES, and other stuff</b> <p> <p>I've started work on SHA-256, SHA-384, and SHA-512, in addition to an implementation of Rijndael. This is part of the infrastructure for HotStepper. Specifically, it's part of a port of Eric Hopper's <a href="http://www.cakem.net/" >CAKE</a> package that will be used to provide security for remote administration of HotStepper. <p> <p>Eric's reference code is called BirthdayCAKE, and the Squeak/ST port will most likely be called CupCAKE. <p> <b>Credit where credit is due</b> <p> <p>I'd like to say a big thank you to jm for his ThirtyTwoBitRegister class, though. It will make the crypto end of things much easier, and looks extremely well built.

While browsing <tt>System-Compression</tt> I found <tt>GZipConstants</tt>, and the rest is history. Needless to say, this will make things much easier for HotStepper. <p> <b><tt>System-Archives</tt></b> <p> <p>I'll have to check SM2 to be sure, but I don't remember seeing a package for interfacing to the Unix tar file format there. There are placeholders in <tt>System-Archives</tt>, though. I'll have to dig around a bit, as I don't want to reinvent the wheel, especially because if it's been done already, it's probably been done by someone way smarter than me. ^_^
