Properties
byte[]	ClientDataHash = default! [get, set]
	SHA-256 hash of the client data JSON. Required parameter (CTAP2 key: 0x01). 32-byte hash of ClientData JSON. Used to bind the credential to the current operation.
uint?	EnterpriseAttestation [get, set]
	If the EnterpriseAttestation parameter is absent, attestation’s privacy characteristics are unaffected, regardless of whether the enterprise attestation feature is presently enabled. If present with a valid value, the usual privacy concerns around attestation batching may not apply to the results of this operation and the platform is requesting an enterprise attestation that includes uniquely identifying information.
List< PublicKeyCredentialDescriptor >?	ExcludeList [get, set]
	List of existing credentials to exclude. Optional parameter (CTAP2 key: 0x05). Prevents creation of duplicate credentials for the same RP/user pair.
Dictionary< string, object >?	Extensions [get, set]
	Requested authentication extensions. Optional parameter (CTAP2 key: 0x06). Dictionary of extension identifiers to extension-specific parameters (e.g., credProtect, hmac-secret).
Dictionary< string, object >?	Options [get, set]
	Authenticator options.
byte?[]	PinUvAuthParam [get, set]
	PIN/UV authentication signature. Optional parameter (CTAP2 key: 0x08). HMAC-SHA256 of clientDataHash using shared secret.
uint?	PinUvAuthProtocol [get, set]
	Selected PIN/UV protocol version. Optional parameter (CTAP2 key: 0x09). Must match protocol version used during key agreement and PIN operations.
List< PublicKeyCredentialParameters >	PubKeyCredParams = [] [get, set]
	List of supported public key algorithms. Required parameter (CTAP2 key: 0x04). Must contain at least one algorithm the authenticator supports (e.g., ES256, RS256). Ordered by RP preference.
PublicKeyCredentialRpEntity	Rp = new() [get, set]
	Relying Party (RP) entity information. Required parameter (CTAP2 key: 0x02). Contains RP ID and display information. Must match the RP ID used in subsequent authentication requests.
PublicKeyCredentialUserEntity	User = new() [get, set]
	User account information. Required parameter (CTAP2 key: 0x03). Contains user handle and display data. User ID must be unique within the RP domain.

Property Documentation

ClientDataHash

byte [] CrescendoDLL.PCSC.FIDODataStructures.MakeCredentialRequest.ClientDataHash = default!

getset

SHA-256 hash of the client data JSON. Required parameter (CTAP2 key: 0x01). 32-byte hash of ClientData JSON. Used to bind the credential to the current operation.

EnterpriseAttestation

uint? CrescendoDLL.PCSC.FIDODataStructures.MakeCredentialRequest.EnterpriseAttestation

getset

If the EnterpriseAttestation parameter is absent, attestation’s privacy characteristics are unaffected, regardless of whether the enterprise attestation feature is presently enabled. If present with a valid value, the usual privacy concerns around attestation batching may not apply to the results of this operation and the platform is requesting an enterprise attestation that includes uniquely identifying information.

ExcludeList

List<PublicKeyCredentialDescriptor>? CrescendoDLL.PCSC.FIDODataStructures.MakeCredentialRequest.ExcludeList

getset

List of existing credentials to exclude. Optional parameter (CTAP2 key: 0x05). Prevents creation of duplicate credentials for the same RP/user pair.

Extensions

Dictionary<string, object>? CrescendoDLL.PCSC.FIDODataStructures.MakeCredentialRequest.Extensions

getset

Requested authentication extensions. Optional parameter (CTAP2 key: 0x06). Dictionary of extension identifiers to extension-specific parameters (e.g., credProtect, hmac-secret).

Options

Dictionary<string, object>? CrescendoDLL.PCSC.FIDODataStructures.MakeCredentialRequest.Options

getset

Authenticator options.

Optional parameter (CTAP2 key: 0x07). Common options:

• rkResident key (default: false)
• uvUser verification (default: false)

PinUvAuthParam

byte? [] CrescendoDLL.PCSC.FIDODataStructures.MakeCredentialRequest.PinUvAuthParam

getset

PIN/UV authentication signature. Optional parameter (CTAP2 key: 0x08). HMAC-SHA256 of clientDataHash using shared secret.

PinUvAuthProtocol

uint? CrescendoDLL.PCSC.FIDODataStructures.MakeCredentialRequest.PinUvAuthProtocol

getset

Selected PIN/UV protocol version. Optional parameter (CTAP2 key: 0x09). Must match protocol version used during key agreement and PIN operations.

PubKeyCredParams

List<PublicKeyCredentialParameters> CrescendoDLL.PCSC.FIDODataStructures.MakeCredentialRequest.PubKeyCredParams = []

getset

List of supported public key algorithms. Required parameter (CTAP2 key: 0x04). Must contain at least one algorithm the authenticator supports (e.g., ES256, RS256). Ordered by RP preference.

Rp

PublicKeyCredentialRpEntity CrescendoDLL.PCSC.FIDODataStructures.MakeCredentialRequest.Rp = new()

getset

Relying Party (RP) entity information. Required parameter (CTAP2 key: 0x02). Contains RP ID and display information. Must match the RP ID used in subsequent authentication requests.

User

PublicKeyCredentialUserEntity CrescendoDLL.PCSC.FIDODataStructures.MakeCredentialRequest.User = new()

getset

User account information. Required parameter (CTAP2 key: 0x03). Contains user handle and display data. User ID must be unique within the RP domain.
