JSON Web Key (JWK) Thumbprints [RFC7638] are a URL-safe representation of a hash value over a JSON Web Key (JWK). This specification defines a URI prefix indicating that the portion of the URI following the prefix is a JWK Thumbprint. This enables JWK Thumbprints to be communicated in contexts requiring URIs, including in specific JSON Web Token (JWT) [RFC7519] claims.¶
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in BCP 14 [RFC2119] [RFC8174] when, and only when, they appear in all capitals, as shown here.¶
The following URI prefix is defined to indicate that the portion of the URI following the prefix is a JWK Thumbprint:¶
urn:ietf:params:oauth:jwk-thumbprint
¶
The prefix is followed by a colon and a JWK Thumbprint value to form a URI representing a JWK Thumbprint.¶
Section 3.1 of [RFC7638] contains the following example JWK Thumbprint value:¶
NzbLsXh8uDCcd-6MNwXF4W_7noWXFZAfHkxZsRGC9Xs¶
A complete JWK Thumbprint URI using the above JWK Thumbprint is:¶
urn:ietf:params:oauth:jwk-thumbprint:NzbLsXh8uDCcd-6MNwXF4W_7noWXFZAfHkxZsRGC9Xs¶
The security considerations of [RFC7638] also apply when using this specification.¶
This specification registers the following value in the IANA "OAuth URI" registry [IANA.OAuth.Parameters] established by [RFC6755].¶
Use cases for this specification were developed in the OpenID Connect Working Group of the OpenID Foundation. Specifically, its use is planned in future versions of the [SIOPv2] specification.¶
