Describe the change
Improve fallback tag handling. The fallback tag should handle long digest algorithms, and should not output invalid tag characters.
How to verify it
There shouldn't be any code paths that are able to reach this change (since sha256 and sha512 are the two registered algorithms and were already correctly handled).
