You may be thinking about the 8048 chip that Intel programmed to do DES enc=
oding/decoding. I believe it was real slow (equivalent to around 100 baud I=
IRC) and required all sorts of clearances to be allowed to purchase it.

These days I think everyone 'just' puts the relevant crypto engine inside a=
n FPGA - its fast, relatively secure and makes for one chip with everything=
 including buffer ram in it.

There is code around for doing it on micros, Microchip sells a CD or downlo=
ad to go with their various app notes of the crypto schemes they support. T=
he CD is a nominal cost, but they have to do it that way so that distributi=
on of the source code can be controlled for ITAR purposes.
