That's very strange. I uploaded the DESPlugin I built with the Cog tools 
to http://leves.web.elte.hu/cryptography/cogplugins/DESPlugin.dll . The 
plugin is built from the sources linked here: 
http://lists.squeakfoundation.org/pipermail/squeak-dev/2010-July/152005.html 
. All tests are green with the plugin.

The DESPlugin I used to use with SqueakVM is here: 
http://leves.web.elte.hu/cryptography/DESPlugin.dll

Please check if you get errors with these plugins too.
