Introduction This document updates the Introduction in Section 1, the Name Constraints certificate extension discussion in Section 4.2.1.10, and the Processing Rules for Internationalized Names in Section 7 of RFC 5280 [RFC5280] to provide alignment with the 2008 specification for Internationalized Domain Names (IDNs) and add support for internationalized email addresses in X.509 certificates. An IDN in Unicode (native character) form contains at least one U-label [RFC5890]. With one exception, IDNs are carried in certificates in ACE-encoded form. That is, all U-labels within an IDN are converted to A-labels. Conversion of a U-label to an A-label is described in [RFC5891]. The GeneralName structure supports many different name forms, including otherName for extensibility. RFC 8398 [RFC8398] specifies the SmtpUTF8Mailbox for internationalized email addresses, which includes IDNs with U-labels.Show full document text
