ConfigureChallengeResponse Class
Namespace: Yubico.YubiKey.Otp.Operations Assembly: Yubico.YubiKey.dllConfigures a YubiKey's OTP slot to perform challenge-response using either the Yubico OTP or the HMAC-SHA1 algorithm.
public class ConfigureChallengeResponse : OperationBase<ConfigureChallengeResponse>Remarks
This class is not to be instantiated by non-SDK code. Instead, you will get a reference to an instance of this class by calling ConfigureChallengeResponse(Slot).
Once you have a reference to an instance, the member methods of this class can be used to chain together configurations using a builder pattern.
Challenge-response mode needs to either have the UseHmacSha1ChallengeResponseMode(bool) or the UseYubicoOtpChallengeResponseMode(bool) setting selected.
Fields
| Name | Description |
|---|---|
| HmacSha1KeySize | The key for an HMAC-SHA1 operation is 20 bytes. |
| YubiOtpKeySize | The key for a Yubico OTP operation is 16 bytes. |
Methods
| Name | Description |
|---|---|
| ExecuteOperation() | Execute the operation here. |
| GenerateKey(Memory<byte>) | Generates a cryptographically random series of bytes as the key for the credential. |
| PreLaunchOperation() | Validate all settings and choices here. |
| SetAllowUpdate(bool) | Allows certain non-security related settings to be modified after the configuration has been written. |
| UseButton(bool) | Require user acceptance by touching the YubiKey button for challenge-response operations |
| UseHmacSha1() | Configures the challenge-response to use the HMAC-SHA1 algorithm. |
| UseKey(ReadOnlyMemory<byte>) | Explicitly sets the key of the credential. |
| UseSmallChallenge(bool) | Set when the HMAC challenge will be less than 64-bytes. |
| UseYubiOtp() | Configures the challenge-response to use the Yubico OTP algorithm. |
