- amanj41 3y agoI'm assuming based on the demo video that the private key is encrypted via the "CVC" code. Not great security but enough that someone would need at least a little while to brute force. Perhaps a solution where you only load a little cash onto it
- nvk 3y agoNo. It's a signed message.
- ada1981 3y agoBut if I replay the signaled message and have the code? I must be confused how this works.
