Why don't we get just get rid of the backwards-compatible (with a
previous version of PEP 376) "hexdigest defaults to md5" syntax, and
require name=base64 digest. Is there any code that parses the PEP 376
base64 is not hard. I was a little surprised that the optional-padding
versions were not already in the standard library.
pad = b'=' * (4 - (len(data) & 3))
return base64.urlsafe_b64decode(data + pad)
