Web-based Digital Certificates And Pkcs12 Package Download Software Development

Now the computer technology already has the widespread application in each domain,and the networking progressed unceasingly by leaps and bounds with a high speed, people'needs of the hardware and software resources are in unceasing inflation. Going with the develop of the technology, many tools appear such as handset, PDA, office and family's desktop computer, notebook computer , which also could support the certificate operation. When the user simultaneously has many such equipment, how can install the certificate and the private key both securely and simply on all equipment? This is the question which this system must solve.Through this system, the user may directly download digital certificate and PKCS#12 package through the homepage, who may safely and simply move the certificate and the key,saving tedious work which is installed the certificate and the private key on all equipment.The certificate and the private key which are centrally preservation(trust) on the roaming server which may trust, can be downloaded by the user when they need, but in this system the roams the server and the client is the identical one.The goal of this design is to study the elementary knowledge of the information security, the key point is to study the computer cryptology and the PKI aspect knowledge,also to grasp the PKCS#12 package of structure. And request to grasp the ASP technology and a method of using VC++ to compile ActiveX control. The key is to undo the PKCS#12 package correctly, and after undoing the PKCS#12 package, it must be able to use the gain digital certificate and the corresponding private key correctly in Windows. Moreover, The ActiveX control must be able to be downloaded correctly,which do not appear the wrong prompt.
