Hi Juan! I'm happy someone has expressed interest in actually having a totally-secure database! That is exactly where Magma is headed as I am currently in the process of upgrading the code to tightly integrate with a totally new version of KryptOn.
(I have just replace the year-old KryptOn page with a total-rewrite; an early draft of the new documentation which clearly articulates the philosophy, ideas and basic usage of KryptOn).
http://wiki.squeak.org/squeak/5785
One thing not mentioned yet in the above documentation is how will Magma (or any other KryptOn program) provide total transparency OR total security via the same code. If security is not needed or wanted, then people want it to be invisible.
That's the promise I'm fulfilling now; the existing Magma 1.0 API's will be preserved by utilizing the "anonymous" MakoNode, so that legacy Magma programs can remain basically unchanged. (The above link describes what is a MakoNode). Magma treats the anonymous node just as any other (non-anonymous) node so this design allows clean code; i.e., no "isAnonymous ifTrue:[] ifFalse:[]" case-logic; all the security code is always exercised either way, but the anonymous node just specifies much smaller keys so that performance is not compromised.
Ability to have a secure database will open up the final phase of Magma development before I can finally "go live"; support for 2-tier programs. This will be needed for creating a keyword-indexed archive of the full history of the Squeak mailing list, accessible from within the image, not just through a web browser.
The version of Magma/KryptOn that was posted last January is just an initial prototype/sketch of such an integration; I would ignore it because so much has been upgraded since then which I will be posting soon.
The design is complete but I still have a fair amount of implementation work to be completed, so it may be another month or two depending.. but it is my top priority, stay tuned..

Hello. I was using Magma (magmaVersion = 8). I want to implement some security in my application so after installing KryptOn-cmm.26 I ran into dependency problems, so as there isn't enough documentation of how to install it (at least isn't enough clear for me), I've installed all the packages from the repository (http://kilana.unibe.ch:8888/KryptOn). I have to ask, which packages and in what order should I install in order to this works properly?
I've seen some packages complements (loose methods?) their magma equivalents. Can anybody give a description of the packages inside this repository? And when it's necessary to install? I mean something really simple like "This implements X functionality" "Install this when you want X (fuzzy searching, handling exceptions, etc)." or "This is/could be needed by X"

The following bug report was generated after executing this expression:

(before installing KryptOn, it worked fine)
