I am generating a valid SHA512 fingerprint, so I know my code is creating a byte array of the Signature Key and correctly generating the SHA512 hash for that.

Now I am trying to validate a relay response for SIM with the 30 field message separated by ^ and I can not get the same hash as x_sha2_hash.

What I need is an example of a signature key, 30 field message, and resulting hash so I can test my implementation.
