RFC 8484, "DNS Queries over HTTPS (DoH)", October 2018

Source of RFC: doh (art)

Errata ID: 5603
Status: Reported
Type: Technical

Reported By: Carsten Bormann
Date Reported: 2019-01-15

Section 4.1 says:

   The URI Template defined in this document is processed without any
   variables when the HTTP method is POST.  When the HTTP method is GET,
   the single variable "dns" is defined as the content of the DNS
   request (as described in Section 6), encoded with base64url
   [RFC4648].

It should say:

   The URI Template defined in this document is processed without any
   variables when the HTTP method is POST.  When the HTTP method is GET,
   the single variable "dns" is defined as the content of the DNS
   request (as described in Section 6), encoded with base64url
   [RFC4648]. Padding characters for base64url MUST NOT be included.

Notes:

Note that Section 6 does say the same thing for a different usage of base64url, and note that the examples in 4.1.1 even explicitly state this, but the text that states the usual deviation from the default of RFC 4648 should be in the defining part as well. (This is almost, but not quite, an editorial erratum.)
