What: /sys/kernel/debug/turris-mox-rwtm/do_sign
Date: Jun 2020
KernelVersion: 5.8
Contact: Marek Behún <marek.behun@nic.cz>
Description: (W) Message to sign with the ECDSA private key stored in
device's OTP. The message must be exactly 64 bytes (since
this is intended for SHA-512 hashes).
(R) The resulting signature, 136 bytes. This contains the R and
S values of the ECDSA signature, both in big-endian format.
