[Defect]: Duplicate MD4 and MD5 family entries in cryptography registry #878
Description
Describe the defect
The cryptography registry currently contains duplicate family entries for MD4 and MD5.
Expected behavior
Each algorithm family should appear only once in the registry.
Actual behavior
MD4 and MD5 each appear more than once as separate family entries.
Proposed fix
Remove the duplicate MD4 and MD5 family entries and keep a single canonical definition for each.
Additional context
This is a registry consistency cleanup only.
