TodayвЂ™s Web browsers do not have implemented functionality for the signing of attached files when they are sent from the client to the Web server. The Problem of Digital Signing in a Web-Based Environment with a Smart CardДocument signing with a smart card in a userвЂ™s Web browser (form fields, forms, files, and other) is an ongoing problem for which there is no standard solution, regardless of the platform and the Web browser type or version. This article expands upon the Nakov Document Signer, found at NakovDocumentSigner, but this article will add some new functionality-signing documents in a Web environment with a smart card. The signing was performed with a local file that contains the clientвЂ™s certificate and its private key, stored in the PKCS#12 file format (file with a PFX extension). On the server side, there was a J2EE Web application that received the signed files and verified their digital signature and the certificate. The system was based on a Java applet that used a Web browser to send files.

In an earlier article ( NakovDocumentSigner: A System for Digitally Signing Documents in Web Applications)В a system was presented to digitally sign documents in a Web-based environment. Private keys in the smart cards can be used to encrypt and sign data but cannot be extracted out of the card. Smart cards are used to securely protect sensitive information such as private keys and certificates and provide better security because of the inability to copy the information stored in them. Certificates are issued by certification authorities and can be stored in a file or on a smart card. Signing documents requires the user to have a digital certificate along with a corresponding private key.
