服务器上的php javascript java小程序智能卡签名pdf

我正在制作一个php应用程序，其中我在服务器上生成了pdf文件，需要由2到60人使用智能卡（使用智能卡阅读器）进行数字签名

一个简单的按钮，上面写着

签名

然后，如果用户在reader应用程序中没有智能卡，则表示：

插入卡片

新弹出窗口包含：

输入引脚

所有这些都以：

文件签署了

---

这可以做到吗？如何做到？

您需要一些在用户计算机上运行的东西，这些东西可以从它的常规沙盒中释放出来，比如一个签名的java小程序。有了这样的东西，一些javascript+AJAX和与服务器的来回通信，您当然可以做到您所说的

您可能必须从用户的计算机上载该文件

e、 g

一、 身为比利时公民，也有一种智能卡类型的，可用于在网上签署文件或通过

---

这是否容易，现在这是另一个问题

我使用bouncy castle和itext libs完成了小程序。我遇到的问题主要是在我的小程序和libs上签名。这是通过在Eclipse中使用Ant解决的。小程序可以在。
