- CLA = 0x80
- INS = 0xC1
- P1 = 0x00
- P2 = 0x00
- Data = a sequence of 32-bit integers
- Response SW = 0x9000 on success, 0x6A80 if data is invalid
- Preconditions: Secure Channel must be opened, user PIN must be verified
Sets the given sequence of 32-bit integers as a PIN-less path. When the current derived key matches this path, SIGN will work even if no PIN authentication has been performed. An empty sequence means that no PIN-less path is defined.
