RFC 9449: Hash of the access token. The value MUST be the result of a base64url encoding (as defined in Section 2 of RFC7515 the SHA-256 hash of the ASCII encoding of the associated access token's value.

RFC 7519: The "aud" (audience) claim identifies the recipients that the JWT is intended for. Each principal intended to process the JWT MUST identify itself with a value in the audience claim. If the principal processing the claim does not identify itself with a value in the "aud" claim when this claim is present, then the JWT MUST be rejected. In the general case, the "aud" value is an array of case- sensitive strings, each containing a StringOrURI value. In the special case when the JWT has one audience, the "aud" value MAY be a single case-sensitive string containing a StringOrURI value. The interpretation of audience values is generally application specific. Use of this claim is OPTIONAL.

OID4VP: This claim contains the confirmation method as defined in RFC7800. It MUST contain a JWK as defined in Section 3.2 of RFC7800. This claim determines the public key for which the corresponding private key the Verifier MUST proof possession of when presenting the Verifier Attestation JWT. This additional security measure allows the Verifier to obtain a Verifier Attestation JWT from a trusted issuer and use it for a long time independent of that issuer without the risk of an adversary impersonating the Verifier by replaying a captured attestation.

RFC 7519: The "exp" (expiration time) claim identifies the expiration time on or after which the JWT MUST NOT be accepted for processing. The processing of the "exp" claim requires that the current date/time MUST be before the expiration date/time listed in the "exp" claim. Implementers MAY provide for some small leeway, usually no more than a few minutes, to account for clock skew. Its value MUST be a number containing a NumericDate value. Use of this claim is OPTIONAL.

RFC 9449: The value of the HTTP method (Section 9.1 of RFC9110) of the request to which the JWT is attached.

RFC 9449: The HTTP target URI (Section 7.1 of RFC9110) of the request to which the JWT is attached, without query and fragment parts.

RFC 7519: The "iat" (issued at) claim identifies the time at which the JWT was issued. This claim can be used to determine the age of the JWT. Its value MUST be a number containing a NumericDate value. Use of this claim is OPTIONAL.

RFC 7519: The "iss" (issuer) claim identifies the principal that issued the JWT. The processing of this claim is generally application specific. The "iss" value is a case-sensitive string containing a StringOrURI value. Use of this claim is OPTIONAL.

RFC 7519: The "jti" (JWT ID) claim provides a unique identifier for the JWT. The identifier value MUST be assigned in a manner that ensures that there is a negligible probability that the same value will be accidentally assigned to a different data object; if the application uses multiple issuers, collisions MUST be prevented among values produced by different issuers as well. The "jti" claim can be used to prevent the JWT from being replayed. The "jti" value is a case- sensitive string. Use of this claim is OPTIONAL.

RFC 7519: The "nbf" (not before) claim identifies the time before which the JWT MUST NOT be accepted for processing. The processing of the "nbf" claim requires that the current date/time MUST be after or equal to the not-before date/time listed in the "nbf" claim. Implementers MAY provide for some small leeway, usually no more than a few minutes, to account for clock skew. Its value MUST be a number containing a NumericDate value. Use of this claim is OPTIONAL.

OID4VCI: OPTIONAL. Status mechanism for the Wallet Attestation as defined in ietf-oauth-status-list.

RFC 7519: The "sub" (subject) claim identifies the principal that is the subject of the JWT. The claims in a JWT are normally statements about the subject. The subject value MUST either be scoped to be locally unique in the context of the issuer or be globally unique. The processing of this claim is generally application specific. The "sub" value is a case-sensitive string containing a StringOrURI value. Use of this claim is OPTIONAL.

OID4VCI: OPTIONAL. String containing a URL to get further information about the Wallet and the Wallet Provider.

OID4VCI: OPTIONAL. String containing a human-readable name of the Wallet.
