Abstract

This specification defines a method for computing a hash value (a.k.a. digest) over a JSON Web Key (JWK) [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, for instance, by using the base64url-encoded JWK Thumbprint value as a "kid" (key ID) value.
