Not if the private key is stored in a secure hardware token.
- Tortoise 13y agoCan you tell the difference between a secure hardware token and a fake secure hardware token? I suppose if you try to extract the secret key and the token destroys it, it's pretty secure. Of course, you just lost all your money. I can't think of a non-destructive test.
- donaldc 13y agoWould you be willing to bet $147M that someone hadn't figured out a way around that hardware security? I wouldn't..
- bigiain 13y agoHow does the key get into the token, and how do you know there wasn't a copy made before that?
- Beltiras 13y agoSIM card f.ex.
- pantaril 13y agoFor example Trezor hardware wallet ( http://www.bitcointrezor.com/ http://www.bitcointrezor.com/ ) generates its private key when it is first initialized. This way, the key never exists outside of the wallet.
- bigiain 13y agoNot sure that solves he upthread probem. If I give you a Treznor hardware wallet containing a private key to $150million worth of bitcoins - would you trust me not to have anther copy of that key? Or would you transfer them immediately to a wallet with a private key I could never possibly have known?
- nullc 13y agoTrezor supports exporting the key for backup purposes.
