Question

For our back-matter resources in OSCAL models, we have been generating SHA-384 hashes of files for the hash objects. We haven't been able to get the resulting hash to be 48 characters with this algorithm. The validation constraints require SHA-384 hashes to be exactly 48 characters. We are currently utilizing the the hashlib package from the python standard library, which generates a 96 character SHA-384 hash. We were wondering if this might be an incorrect regular expression used in validation, or if not, if you had any suggestions for generating a 48 character SHA-384 hash.
