Subject: JSON Web Key (JWK) Thumbprint is now RFC 7638
The JSON Web Key (JWK) Thumbprint specification is now RFC \
7638<http://www.rfc-editor.org/info/rfc7638>. The abstract describes the \
specification as follows:
This specification defines a method for computing a hash value over a JSON Web Key \
(JWK). It defines which fields in a JWK are used in the hash computation, the method \
of creating a canonical form for those fields, and how to convert the resulting \
Unicode string into a byte sequence to be hashed. The resulting hash value can be \
used for identifying or selecting the key represented by the JWK that is the subject \
of the thumbprint.
Thanks to James Manger<https://www.linkedin.com/pub/james-manger/3b/561/979>, John \
Bradley<http://www.thread-safe.com/>, and Nat Sakimura<http://nat.sakimura.org/>, all \
of whom participated in security discussions that led to the creation of this \
specification. Thanks also to the JOSE working \
group<http://datatracker.ietf.org/wg/jose/charter/> members, chairs, area directors, \
and other IETF members who contributed to the specification.
A JWK Thumbprint is used as the "sub" (subject) claim value in OpenID Connect \
self-issued ID Tokens<http://openid.net/specs/openid-connect-core-1_0.html#SelfIssuedResponse>.
