Type: Technical
Reported by: Brian Wellington <bwelling@akamai.com>

Section: A.3

Original Text
-------------
example.      86400  IN  ZONEMD  2018031900 241 1 (
                                 e1846540e33a9e41
                                 89792d18d5d131f6
                                 05fc283e )


Corrected Text
--------------
<A ZONEMD record with a digest of length 48>

Notes
-----
2.2.3 defines Hash Algorithm 1 as SHA384, and says that "the size of the Digest field is 48 octets". There is nothing in 2.2.3 (or 2.2.2, where Scheme is defined) that indicates that Scheme and Hash Algorithm are dependent on each other, so the fact that the Scheme value (241) is private should have no effect on the digest computed by Hash Algorithm 1.

Instructions:

This erratum is currently posted as "Reported". If necessary, please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party
