OCRA Configuration
The control accepts one or more of the following configuration settings. Configuration settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.OCRA Configuration Settings
CounterHex: The counter value as a hexadecimal string.This setting may be used instead of Counter to supply the counter value. This is specified as a Hexadecimal string and may be used to provide large values like "FFFFFFFFFFFFFFFF". | |||||||
CurrentTime: The current time in milliseconds.This setting specifies the current time in milliseconds since the Unix epoch (January 1, 1970). By default the control will use the system time when CalculateResponse or VerifyResponse is called and RequireTimeStamp is True. This setting overrides the value returned by the system. | |||||||
PasswordHashAlgorithm:
The password hash algorithm.This setting specifies the password hash algorithm. Possible values are:
| |||||||
RequireSessionInfo:
Whether to use session information.This setting specifies whether session info is required to create the response.
This may be set before calling CreateChallenge, when the OCRASuite is generated. When OCRASuite is assigned this value is updated to reflect the options specified in the OCRASuite | |||||||
SessionInfo: The session information.This setting specifies the session info when RequireSessionInfo is set to True. This value should be specified before calling CalculateResponse or VerifyResponse, and should be of length SessionInfoLength. | |||||||
SessionInfoLength:
The length of the session information.This setting specifies the length of the session information.
This may be set before calling CreateChallenge, when the OCRASuite is generated. When OCRASuite is assigned this value is updated to reflect the options specified in the OCRASuite Common values are 64, 128, 256, and 512. | |||||||
TimeStepSize: The time step.The size of the time step. The default value is 1. | |||||||
TimeStepUnit:
The time step unit.This setting specifies the time step unit. Possible values are:
|
Base Configuration Settings
CodePage:
The system code page used for Unicode to Multibyte translations.The default code page is Unicode UTF-8 (65001).

UseInternalSecurityAPI: Tells the control whether or not to use the system security libraries or an internal implementation. By default the control will use the system security libraries to perform cryptographic functions. Setting this to True tells the control to use the internal implementation instead of using the system's security API. |
