The following errata report has been submitted for RFC6455,
"The WebSocket Protocol".

--------------------------------------
You may review the report below and at:
http://www.rfc-editor.org/errata_search.php?rfc=6455&eid=3150

--------------------------------------
Type: Technical
Reported by: Robert Munyer <robertm-cooppith@stackframe.com>

Section: 4.1

Original Text
-------------
AQIDBAUGBwgJCgsMDQ4PEC==

Corrected Text
--------------
AQIDBAUGBwgJCgsMDQ4PEA==

Notes
-----
The "test vector" for Sec-WebSocket-Key encoding, provided in RFC 6455 section 4.1, is wrong.  It was processed by a base 64 encoder that was "improperly implemented" as mentioned in RFC 4648 section 3.5.  Pad bits were not set to zero, which is a "MUST" requirement in RFC 4648, and was also required by many other RFCs, going back to RFC 989 in the 1980s.  In the string "AQIDBAUGBwgJCgsMDQ4PEC==", the final C should be changed to A.

In a Sec-WebSocket-Key header sent by a properly implemented client, the last letter will always be A, Q, g or w.

Instructions:

This errata 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 (IESG)
