Realized the other action item I was assigned to from the interim meeting was
email canonicalization for SMIMEA. I believe it stems from Viktor Dukhovni's
email to the endymail list:
http://www.ietf.org/mail-archive/web/endymail/current/msg00134.html
I was wondering if we can borrow a page from RFC 4034 Section 6.2 and include
text in the draft Section 3, item 1 in the numbered list:
1. The user name (the "left-hand side" of the email address, called
the "local-part" in the mail message format definition [RFC2822]
and the "local part" in the specification for internationalized
email [RFC6530]), is hashed using the SHA2-224 [RFC5754]
algorithm (with the hash being represented in its hexadecimal
representation, to become the left-most label in the prepared
domain name. This does not include the "@" character that
separates the left and right sides of the email address. The
string that is used for the local part is a Unicode string
encoded in UTF-8 **with all upper case letters converted to their
corresponding lower case letters where appropriate.**
The text between the '**' is new. The goal is to prevent a situation when the
email address is "[email protected]" and the SMIMEA is created using
"jrandom" as the user name. Would this be enough, or are there scripts where
this would result in different or potentially conflicting owner names?
