Ok, I did some measurements. Results are pretty disappointing.
Squeak on my AMD 3800+ processor encrypts 32 KBytes using 3DES CBC mode
in about 8 seconds - unusable for anything but a proof-of-concept.
Therefore I think that DES (and maybe some other small cryptographic
primitives) should be part of the base VM.
======================================

Just to clarify, is this a discussion regarding where a plugin or DLL
belongs, or regarding whether we need one at all?
