Hi there,

I'm trying to pick a hardware token / smart card that supports the elliptic curve used in Bitcoin (secp256k1). I'm having some trouble finding one - I've seen SafeNet's smart card that claims to have p256, but my understanding is that that named curve is slightly different than the one needed here. I thought I saw a JavaCard software implementation floating around somewhere, but random unvetted crypto implementations make me nervous.

Can anyone recommend a solid smart card or hardware token that has FIPS / CC certification with support for secp256k1?
