RFC 8226 specifies the use of certificates for Secure Telephone
Identity Credentials; these certificates are often called "Secure
Telephone Identity Revisited (STIR) Certificates". RFC 8226 provides
a certificate extension to constrain the JSON Web Token (JWT) claims
that can be included in the Personal Assertion Token (PASSporT), as
defined in RFC 8225.  If the PASSporT signer includes a JWT claim
outside the constraint boundaries, then the PASSporT recipient will
reject the entire PASSporT. This document updates RFC 8226; it
provides all of the capabilities available in the original
certificate extension as well as an additional way to constrain the
allowable JWT claims.  The enhanced extension can also provide a list
of claims that are not allowed to be included in the PASSporT.

This document is a product of the Secure Telephone Identity Revisited Working Group of the IETF.

This is now a Proposed Standard.
