Signing With A Contact Smart Card-sql2005安装图解

Business You can a sign documents using a Contact Smart Card through a user’s web browser using a Java applet. Throughout this article, you will discover how to build an applet that is based on the Sun PKCS#11 Provider, a cryptographic provider that is part of J2SE 5.0 – Card Embosser . Signing documents requires the user to have a digital certificate along with a corresponding private key. Certificates are issued by certification authorities and can be stored in a file or on a Contact Smart Card – Card Embossing Machine . Contact 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. Private keys in the Contact Smart Cards can be used to encrypt and sign data but cannot be extracted out of the card. Background In an earlier article (NakovDocumentSigner: A System for Digitally Signing Documents in Web Applications) a system was presented to digitally sign documents in a Web-based environment. The system was based on a Java applet that used a Web browser to send files. On the server side, there was a J2EE Web application that received the signed files and verified their digital signature and the certificate. The signing was performed with a local file that contains the client’s certificate and its private key, stored in the PKCS#12 file format (file with a PFX extension).
