I'm pleased to announce the fruit of my cryptography studies!
I've completely reworked the swiki page.

And the shiny new code is on SqueakSource and SqueakMap; much cleaned from that initial alpha version months back.
I hope the months of careful consideration, detailed implementation, and high scrutiny has resulted in something useful or educational to others.
Most of my guidance came from internet resources, but with notable help on difficult design decisions from John McIntosh, Andrew Gaylard, Cees and Goran. Thank you all.
For the sake of confidence in this work, I have created a Swiki page specially inviting KryptOn critique.
