Output a reference string of the ModHex characters 0..15 first.

C#

public const byte SendReferenceString = 1

Returns

System.Byte

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 the UseAlphaNumericPassword flag, 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".
