3.10.4.3 Secret key information structure, missing field for hash algorithm #3

Open creiter32 opened 3 years ago

Hi,

I hope it is ok if I ask further questions here, as I have not found another way to contact the authors of the IoT SAFE specification.

The secret key object does not have a field Supported algorithms for hash or something similar allowing the host to determine if the secret key is for HMAC with SHA256, SHA384 or SHA512. What is the intended way to get this information? Or is this an oversight in the specification?
