The "soc id header info" parsed by the python script is as follows

We currently have multiple boards and multiple key pairs, how to find the corresponding key pair through the "soc id header info" obtained in serial port boot mode?

From the "sec cust mpk hash" field we assume that its value is the hash value of the private key, but the hash value we calculate with sha512sum is different from it?

So we want to know how the private key is computed to get "sec cust mpk hash".
