CredentialManagementData Class

Namespace: Yubico.YubiKey.Fido2.Commands Assembly: Yubico.YubiKey.dll

Parses the data returned by the YubiKey after calling one of the authenticatorCredentialManagement subcommands. This class is relevant only to the class in order to extract data from a response.

public class CredentialManagementData : Object

Inheritance System.Object CredentialManagementData

Remarks

When a credential management subcommand is sent to the YubiKey, it returns data encoded following the definition of the authenticatorCredentialManagement response. The FIDO2 standard defines this encoded response as a map of a set of elements. The standard also specifies which subset of the total data is returned by each subcommand.

After calling one of the subcommands, get the data out of the response. It will be an instance of this class. Only those elements the particular subcommand returns will be represented in the object, the rest will be null.

For example, if you call the get credential metadata subcommand, the YubiKey will return the number of discoverable credentials and the maximum number of credentials the YubiKey can yet hold (i.e. the number of remaining slots). Hence, the only two properties with values will be NumberOfDiscoverableCredentials and RemainingCredentialCount. All other properties will be null.
