Note: This page is for customers who are using HTML5 Edition of Dynamic Web TWAIN on Chrome 57+, Firefox 53+.
Aug 02, 2008 Dynamic Web TWAIN HTML5 Edition could work fine with Chrome and Firefox. But on IE 10/11, the browser keeps prompting you to download and install DynamicWebTWAINHTML5Edition. Cause: Dynamic Web TWAIN doesn't work with your IE proxy setting; You are a domain user and the IP 127.0.0.1 is not considered local anymore; Possible solution 1. Dynamic Web TWAIN is a browser-based document scanning SDK specifically designed for web applications. With just a few lines of JavaScript code, you can develop robust applications to scan documents from TWAIN and SANE compatible scanners, edit the scanned images and save them to a local/server file system or document repository.
Symptom:
Even after Dynamic Web TWAIN HTML5 Edition has installed properly and works on earlier versions of Chrome or Firefox, it doesn't work anymore on Chrome 57+ or Firefox 53+ and keep prompting you to download and install it again on a secure page (SSL).
Cause:
All versions before v12.3 use SHA-1 algorithm and commonName matching in certificates. In Chrome 57 or Firefox 53 has officially removed support for SHA-1 certificates. Furthermore, Chrome 58+ has removed the support for commonName matching in SSL certificates. More info can be found on

Solution:
As SHA-1 certificate is indeed insecure and support for it will probably be permanently removed later on in Chrome, Firefox, Edge, etc. At the same time, the commonName matching deprecation will also make the old certificates invalid.
The recommended solution is to upgrade to the latest version of the SDK. If you are not the developer of the scanning application, please contact the application support team for the latest version.
