^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 		(Write) Message to sign with the ECDSA private key stored in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 		        device's OTP. The message must be exactly 64 bytes
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) 		        (since this is intended for SHA-512 hashes).
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) 		(Read)  The resulting signature, 136 bytes. This contains the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 12) 			R and S values of the ECDSA signature, both in
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 13) 			big-endian format.
