Re: [lamps] [Errata Held for Document Update] RFC8398 (5418)

[Corey Bonnell <[e-mail]>]

This erratum is addressed in 8398-bis, albeit a bit differently due to the
use of A-label representation of the first label of the domain part:
https://www.ietf.org/archive/id/draft-ietf-lamps-rfc8398bis-02.html#appendix
-B.

Subject: [lamps] [Errata Held for Document Update] RFC8398 (5418)

The following errata report has been held for document update for RFC8398,
"Internationalized Email Addresses in X.509 Certificates". 

--------------------------------------
You may review the report below and at:

Status: Held for Document Update
Type: Technical

Section: Appendix B

Original Text
-------------
   This non-normative example demonstrates using SmtpUTF8Mailbox as an
   otherName in GeneralName to encode the email address
   "[e-mail]".

      The hexadecimal DER encoding of the email address is:
      A022060A 2B060105 05070012 0809A014 0C12E880 81E5B8AB 40657861
      6D706C65 2E636F6D

      The text decoding is:
        0  34: [0] {
        2  10:   OBJECT IDENTIFIER '1 3 6 1 5 5 7 0 18 8 9'
       14  20:   [0] {
       16  18:     UTF8String '[e-mail]'
             :     }
             :   }

                                 Figure 2

   The example was encoded on the OSS Nokalva ASN.1 Playground and the
   above text decoding is an output of Peter Gutmann's "dumpasn1"
   program.

   This non-normative example demonstrates using SmtpUTF8Mailbox as an
   otherName in GeneralName to encode the email address
   "u+533Bu+751F@u+5927u+5B66.example.com".

   The hexadecimal DER encoding of the block is:
   a0330608 2b060105 05070809 a0270c25 c3a5c28c c2bbc3a7 c294c29f 
   40c3a5c2 a4c2a7c3 a5c2adc2 a62e6578 616d706c 652e636f 6d


   The text decoding is:
     2  51: [0] {
     4   8:   OBJECT IDENTIFIER '1 3 6 1 5 5 7 8 9'
    14  39:   [0] {
    16  37:     UTF8String '..@...example.com'
          :     }
          :   }

   The example was encoded on the OSS Nokalva ASN.1 Playground and the
   above text decoding is an output of Peter Gutmann's "dumpasn1"
   program.

Notes
-----
The OID used in Appendix B does not match the OID for id-on-SmtpUTF8Mailbox
defined in "Appendix A.  ASN.1 Module" and is not mentioned anywhere in the
RFC.

Paul Wouters (AD): Note that it seems different versions of the dumpasn1
tool seem to handle non-ASCII characters in the output differently, so the
tool output can slightly vary from the Reporter's corrected output. The OID
correction has been verified by my and Russ Housley
