SendReferenceString Method

SendReferenceString(bool)

Sends a reference string of the ModHex characters for 0-15 before the fixed or OTP data.

C#

public ConfigureYubicoOtp SendReferenceString(bool setConfig = true)

Parameters

Type	Name	Description
bool	setConfig

Returns

ConfigureYubicoOtp

The current ConfigureYubicoOtp instance.

Remarks

This can be used by the verifying application to verify the mapping of the modhex characters.

For all YubiKeys with a firmware version of 2.0 or later, if set in combination with UseAlphaNumericPassword(bool), this string will be replaced with a shifted character '1' (typically '!' on most keyboard layouts). This can be used to meet strong password requirements where at least one character is required to be a "special character".
