T5244 was the task for old FIPS 140, and the topic was MD5.
We introduced .disabled but its use has been inconsistent (yet), or we have discrepancy in its documentation.
Let us clarify things for non-approved digest algo(s) are supported, and how it is ensured only approved digest algo(s) are in use in signature computation when FIPS enabled.
Note that SHA-1 is special. Its use for hashing is OK, but not for (internal) hashing at signature computation.
