pub fn parse_unblock_pin(
payload: &[u8],
) -> Result<([u8; 8], [u8; 4], [u8; 32]), PayloadError>Expand description
Parse the payload of CommandOpcode::UnblockPin.
Layout: puk (8) || new_pin (4) || io_key (32). The IO key is
the 32-byte I/O Protection Key stored in slot 8, provided by the host
from its local provisioning config. The firmware uses it to perform
the encrypted write of the new PIN hash into slot 5; it is not stored.
Returns (puk, new_pin, io_key).
