Question

我能够在当地使用castle堡jar沟进行加密和加密。我产生了一些关键因素,我想把公用钥匙放在客户(Java和Anderson)和网络服务的私人钥匙上。我得以对电文进行加密和编码,并向网络服务处发送加密信息(在月球网页的主机服务上),但网络服务加密没有在线上安装一个文件。

BouncyCastleProvider bc = new BouncyCastleProvider();

或

Security.addProvider(new BouncyCastleProvider());

bcprov-ext-jdk14-146.jar和bcprov-jdk14-146.jar被列入网上校准目录。

Is there something I can do programmatic to enable this 或does Lunarpages have to do something?

I couldnt even get a stacktrace to print f或me and so I thought I might attempt a different provider to see if I get a better response - the SunJCE.

access denied (java.security.SecurityPermission insertProvider.SunJCE)

java.security.AccessControlContext.checkPermission(AccessControlContext.java:269) java.security.AccessController.checkPermission(AccessController.java:401) java.lang.SecurityManager.checkPermission(SecurityManager.java:524) java.lang.SecurityManager.checkSecurityAccess(SecurityManager.java:1673) java.security.Security.check(Security.java:1307) java.security.Security.insertProviderAt(Security.java:697) java.security.Security.addProvider(Security.java:757) net.wpstudios.tcws.pgp.RSAEncrypt.generateKeys(RSAEncrypt.java:81) javax.servlet.http.HttpServlet.service(HttpServlet.java:165) javax.servlet.http.HttpServlet.service(HttpServlet.java:103) com.caucho.server.http.FilterChainServlet.doFilter(FilterChainServlet.java:96) com.caucho.server.http.Invocation.service(Invocation.java:315) com.caucho.server.http.CacheInvocation.service(CacheInvocation.java:135) com.caucho.server.http.RunnerRequest.handleRequest(RunnerRequest.java:346) com.caucho.server.http.RunnerRequest.handleConnection(RunnerRequest.java:274) com.caucho.server.TcpConnection.run(TcpConnection.java:139) java.lang.Thread.run(Thread.java:534)

Answer 1

Does the FileNotFound exception matter? Obviously the caucho server setup is using access restrictions on adding providers. Never mind that, if you want to develop some application level encryption/decryption you can simply use the bouncy castle crypto API directly. It s not as friendly as the JCE but it is useable enough. This might not work if you want to use a library that in its turn uses the JCA/JCE framework though.

Lunarpages is to change the permissions or add providers manually (using resin.conf, it seems), but it might be hard to change them just for you, unless you are the only one using the Java application server. It never hurts to ask I suppose.
