It is not possible to find digest names that universally match
prior practice.  So likely any recognizable non-confusing names
are sufficient.

For example in OpenSSL the names are:

    #define SN_sha256               "SHA256"
    #define LN_sha256               "sha256"

with no hyphens at all.  So, perhaps surprisingly, I have
no objects to the digest names, it is clear what they mean,
and no single choice matches established practice.
