fast DES information

In a posting to sci.crypt.research, Bruce Schneier indicates
that VLSI's commercial DES chip (the 6868) has a 32 MHz clock
and encrypts data at 256 MB/second.

Bruce also reports that a DEC Alpha 4000/610 can encrypt DES
at 154,000 8-byte encryptions per second.

I mention this only in the context of earlier concerns about getting
DES to encrypt at high speeds.  This is not and must not be misconstrued
as a product endorsement of any sort.
