audience

The "aud" (audience) claim has the same meaning and processing rules as the "aud" claim defined in Section 4.1.3 of RFC7519, except that the value of the audience claim is a StringOrURI when it is not an array or each of the audience array element values is a StringOrURI when the audience claim value is an array. (StringOrURI is defined in Section 2 of this specification.) The Claim Key 3 is used to identify this claim.
