Well, it is a bit moot as far as I can see because the only hit for a card I saw in the first couple pages of a google search was one that cost around US$700 (there were a few other hits but the cards are no longer available...) > An other device which should be interesting in the context of cryptography > is a random numbers generator.

The TPM is also capable of enctyption but it is not intended for bulk encryption, the interface is too slow/limited for that. -- Sent from my NetBSD device.
