During the development of Zn I have regulary tested on Squeak (currently 4.2 #10977), and most of the code works unmodified. Recently, I had another look, and I would like to fix some issues, if possible.

I am not aware of that many versions.
I subclass Announcement, instanciate an Announcer, send #announce: and #on:send:do to it, that's all.
Would Announcements from http://www.squeaksource.com/AXAnnouncements do ? What is the AX variant by the way ? This repository has not seen many recent updates, I assume it still works for Squeal 4.2.

I guess you mean the main Cryptograhy package from http://www.squeaksource.com/Cryptography, I can't seem to find any loading instructions. I will try.

OK

I will just try then.
