Why it is not in the COSE block
Section titled “Why it is not in the COSE block”IANA assigns bare-hash tags at 18300-18811, where the tag for COSE algorithm N is 18556 + N. COSE registers no
CRC-32 and no MD5, and the range of algorithm numbers that block maps is assigned by Standards Action, so neither will
ever appear there. This tag is taken instead from the First Come First Served range, where registration is a form and no
review.
MD5 is carried only to match a file against a catalog, never for integrity. Where these specifications need a digest to be trusted they name SHA-256 directly and offer no choice.
