!!! Overview
[{$pagename}] ([RFC 7638]) defines a method for computing a [hash] value over a [JSON Web Key] ([JWK]).
[{$pagename}] 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.
The [thumbprint] of a [JSON Web Key] ([JWK]) is computed as follows:
* Construct a [JSON] object [RFC 7159] containing only the required members of a [JWK] representing the key and with no whitespace or line breaks before or after any syntactic elements and with the required members ordered lexicographically by the [Unicode] code points of the member names. (This [JSON] object is itself a legal [JWK] representation of the key.)
* [Hash] the octets of the [UTF-8] representation of this [JSON] object with a [Cryptographic Hash Function] H.
For example, [SHA-256] might be used as H. The resulting value is the [{$pagename}] with H of the [JWK].
