Hi Ron,
I believe the plugin is only needed to seed a SecureRandom, otherwise
you can seed it yourself with SecureRandom class>>#key:.

What do you mean by "insecure"? The black-box comment was more
something regurgitated from Ferguson and Schneiers book; (going from
memory here, check your copy) that there is no really secure operating
system so, you have to be careful as your required infrastructure
spreads out of Squeak and into the bowels of the OS. In the case of
DESPlugin I doubt its much of a problem, but I honestly don't know..

Too slow for what? It looks like TripleDES is used just to seed the
SecureRandom so it depends on how often you need to re-seed it..

PS - I don't know that I would call it "my" SecureRandom, I just
improved the API's to allow for other PRNG algorithms. I'll be using
the Fortuna PRNG for my stuff..
