如何让javax.crypto类（如javax.crypto.Cipher）在jboss的servlet上工作？ [英] How do I get javax.crypto classes such as javax.crypto.Cipher to work on a servlet with jboss?

问题描述

我的应用程序验证许可证文件，以使其正常工作。它通过调用javax.crypto.Cipher.getInstance（DES，SunJCE）来解密许可证密钥文件。

My application validates a license file in order for it to work. It does this by calling javax.crypto.Cipher.getInstance("DES","SunJCE") inorder to decipher the license key file.

当我在本地运行我的应用程序时一切工作正常，但是当我使用jboss部署我的应用程序，并到达我想验证servlet上的许可证文件的时候，我收到以下错误：

When I run my application locally everything works fine but when I deploy my application with jboss and get to the point where I want to validate the license file on the servlet, I get the following error:

java.lang.SecurityException: JCE cannot authenticate the provider SunJCE
  at javax.crypto.Cipher.getInstance(DashoA13*..)
  at javax.crypto.Cipher.getInstance(DashoA13*..)

像我说的，它在命令提示符和eclipse中工作正常，但不是作为jboss上的servlet。有人有什么想法我需要做什么？我正在使用jdk 1.6和jboss作为7。

Like I said, it works fine from command prompt and eclipse, but not as a servlet on jboss. Does anybody have any idea what I need to do? I am using jdk 1.6 and jboss as 7.

谢谢

推荐答案

I figured out what was wrong with my code. Earlier in the code for some reason someone did the following:

if (SunJCEinProviders) 
{
Security.removeProvider("SunJCE");
}   

int i = Security.insertProviderAt(new  com.sun.crypto.provider.SunJCE(),1);

所以由于某些原因我们删除了最初的SunJCE提供程序，然后添加了一个新的，未能通过认证。

So for some reason we were removing javas initial SunJCE provider then adding a new one and this new one was failing to be authenticated.
