Integrate challenge input from an image

Mobile Authenticator Studio supports the input of a challenge as a QR code or a Cronto image for authenticators configured in a Challenge/Response operating mode. The image content must be the value of the challenge as generated by the server.

The content of the image can be generated using the Secure Messaging SDK 4.3.5 or later by calling the challenge transaction message body generation functionality in version 1.

Java

publicstatic String generateChallengeTransactionMessageBodyV1(String challenge) throws MessageSDKException

.NET

publicstatic String GenerateChallengeTransactionMessageBodyV1(String challenge)

The image can be generated using the Image Generator SDK 4.3.5 or later by calling either the QR code generation API or the Cronto image API.

Java

publicstatic BWQRCodeResponse generateBWQRCode(int imageSize, String inputValue, int errorCorrectionLevel) throws ImageGeneratorException

publicstatic BufferedImage generateCrontoSign(int squareSize, String inputValue) throws ImageGeneratorSDKException

.NET

publicstatic BWQRCodeResponse GenerateBWQRCode(int imageSize, String inputValue, int errorCorrectionLevel)

publicstatic Bitmap GenerateCrontoSign(int squareSize, String inputValue)
