The following errata report has been submitted for RFC8188,
"Encrypted Content-Encoding for HTTP".

You may review the report below and at:

Notes
-----
This is the same issue as Erata ID 8620 (https://www.rfc-editor.org/errata/eid8620) but for the next example.

This one I'm less sure about. The RFC never explicitly says whether the final padding delimiter is required or not, but, by my reading at least, does strongly imply it is required in several places.

Assuming the final padding delimiter is required, this example should include it.

Instructions:
-------------
This erratum is currently posted as "Reported". (If it is spam, it 
will be removed shortly by the RFC Production Center.) Please
use "Reply All" to discuss whether it should be verified or
rejected. When a decision is reached, the verifying party  
will log in to change the status and edit the report, if necessary.
