Description

If a user's Digipass has been programmed to operate in Challenge/Response authentication mode, the authentication application must generate a random challenge suitable for the user's Digipass, and then prompt the user to enter the proposed challenge into the Digipass authenticator to generate a dynamic password. This function obtains the challenge characteristics information of the user's authenticator application from the authenticator application BLOB and generates the appropriate challenge. The user enters the challenge into the Digipass authenticator to generate a dynamic password that will be validated through the AAL2VerifyPassword API call. ChallengeLength is automatically calculated and is returned to the application.
