Before we start using this component we need to configure some site properties in the espace AltchaConfigs_BL.

Set the values for the following site properties:

• DeleteOldSolutionsInMinutes - This is the value that we will delete old solutions from the database, so it doesn't have resubmits.
• ExpirationInSeconds - Time in seconds that the Altcha solution will expire before we check it. If we put 0 it will not use this validation.
• ALG - Algorithm method. Default value is "SHA256"
• JS_ALG - Algorithm method. Default value is "SHA-256"
• HMAC_ALG - HMAC Algorithm, default value is "HMACSHA256"
• HMAC_KEY - HMAC Key. you can generate your key in a tool like HMAC-SHA256 Online Generator Tool

After this initial configuration, we can start using our Altcha component. To use this component, we should import the WB and configure it like we want.

In the submit action of the screen, you have to call the action VerifyServerAltcha to validate the Altcha solution to check that is a valid.

Optional parameters in the component:

• IsAuto - Automatically verify without user interaction (possible values: onload, onsubmit).
• Expire - The challenge expiration (duration in milliseconds).
• IsHideFooter - Hide the footer.
• IsHideLogo - Hide the ALTCHA logo.
