 If the Wallet requires the Verifier to encrypt the Request Object, it SHOULD use the `jwks` or `jwks_uri` parameter within the `wallet_metadata` parameter to pass the public key for the input to the key agreement. Other mechanisms to pass the encryption key can be used as well. If the Wallet requires an encrypted Authorization Response, it SHOULD specify supported encryption algorithms using the `authorization_encryption_alg_values_supported` and `authorization_encryption_enc_values_supported` parameters.

Each Verifiable Presentation MUST be represented as a JSON string (that is a Base64url encoded value) or a JSON object depending on a format as defined in Appendix A of [@!OpenID.VCI].

 `presentation_submission`:

It contains mappings between the requested Verifiable Credentials and where to find them within the returned VP Token. This is expressed via elements in the `descriptor_map` array, known as Input Descriptor Mapping Objects. These objects contain a field called `path`, which, for this specification, MUST have the value `$` (top level root path) when only one Verifiable Presentation is contained in the VP Token, and MUST have the value `$[n]` (indexed path from root) when there are multiple Verifiable Presentations, where `n` is the index to select. Additional parameters can be defined by Credential Formats, see (#alternative_credential_formats) for details.

 ### Presentation Response
 
-The VP Token contains the base64url encoded `DeviceResponse` CBOR structure as defined in ISO/IEC 18013-5 [@ISO.18013-5] or ISO/IEC 23220-4 [@ISO.23220-4]. Essentially, the `DeviceResponse` CBOR structure contains a signature or MAC over the `SessionTranscript` CBOR structure including the OpenID4VP-specific `Handover` CBOR structure.
