The following errata report has been submitted for RFC8422,
"Elliptic Curve Cryptography (ECC) Cipher Suites for Transport Layer Security (TLS) Versions 1.2 and Earlier".

--------------------------------------
You may review the report below and at:
https://www.rfc-editor.org/errata/eid6002

--------------------------------------
Type: Technical
Reported by: Rich Salz <[email-masked]>

Section: 9

Original Text
-------------
IANA has assigned two values in the "TLS SignatureAlgorithm" registry for ed25519 (7) and ed448 (8) with this document as reference.  This keeps compatibility with TLS 1.3.

Corrected Text
--------------
IANA has assigned two values in the "TLS SignatureAlgorithm" registry for ed25519 (7) and ed448 (8) with DTLS-OK set to true (T) and this document as reference.  This keeps compatibility with TLS 1.3.

Notes
-----
IANA had consulted with Yoav, one of the authors (and a TLS registry expert), who explicitly told them to use DTLS-OK should be "Y".  This also matches the text in the subsequent paragraph.

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
