8*4882a593Smuzhiyun		(Write) Message to sign with the ECDSA private key stored in
9*4882a593Smuzhiyun		        device's OTP. The message must be exactly 64 bytes
10*4882a593Smuzhiyun		        (since this is intended for SHA-512 hashes).
11*4882a593Smuzhiyun		(Read)  The resulting signature, 136 bytes. This contains the
12*4882a593Smuzhiyun			R and S values of the ECDSA signature, both in
13*4882a593Smuzhiyun			big-endian format.
