我正在製作一個php應用程序，我已經在2到60人的服務器上生成了需要用智能卡（使用智能卡讀卡器）digitaly簽名的pdf文件。php javascript java applet服務器上的智能卡簽署pdf
一個簡單的按鈕，上面寫着
註冊...
然後，如果用戶在閱讀器應用程序沒有智能卡說：
插入卡，
一個新的彈出：
輸入引腳，
，所有結束了：
文件簽署。
可以這樣做嗎？

您需要在用戶的計算機上運行，並允許其脫離常規沙箱，如簽名的Java小程序。有了這樣的事情，一些JavaScript + AJAX和來回與您的服務器通信，你當然可以做你正在談論的。
您可能需要從用戶計算機上傳文件。
例如
How to write a java smartcard applet

我，是比利時公民，也有一個智能卡型的id-card，可用於簽署通過網絡文件或提供訪問的東西通過一個applet
這很容易，現在這是另一個問題。 :)

我已經完成了使用彈性城堡和itext庫的applet。我遇到的問題主要是在我的applet和libs的簽名方式。這是通過在Eclipse中使用Ant解決的。該applet可以在http://www.compensatemeonline.com/applet/japplet.html。
