Java JCE cannot authenticate provider BC in jarsplice created jar
提问by Spencer H
I am working on a game and I am using the Slick2D library. I am also using bouncycastle for encryption. Then I use jarsplice to package everything together in a nice executable. And it runs fine until it needs to encrypt something. It gives me a java.lang.SecurityException: JCE cannot authenticate the provider BCAnd I am using a signed jarfile (http://www.bouncycastle.org/download/bcprov-jdk15on-150.jar)
我正在开发一款游戏，并且正在使用 Slick2D 库。我也在使用 bouncycastle 进行加密。然后我使用 jarsplice 将所有内容打包到一个不错的可执行文件中。它运行良好，直到需要加密某些东西。它给了我一个java.lang.SecurityException: JCE cannot authenticate the provider BC我正在使用签名的 jarfile ( http://www.bouncycastle.org/download/bcprov-jdk15on-150.jar)
Here is the stack trace
这是堆栈跟踪

So how do I authenticate the jarfile to run? This is a standalone executable jarfile.
那么如何验证要运行的 jarfile 呢？这是一个独立的可执行 jarfile。

You probably want to register the cryptographic service provider at runtime to ensure the configuration will work for everyone. You can use either of the Security.addProvider() or Security.insertProviderAt() methods. See documentation linked below under "Managing Providers".
您可能希望在运行时注册加密服务提供者，以确保配置适用于所有人。您可以使用 Security.addProvider() 或 Security.insertProviderAt() 方法。请参阅下面“管理提供商”下链接的文档。
Just use addProvider() unless the order of providers is somehow important for you. I saw one contributor commented that you might slot it in at entry #9, but I didn't see evidence that this is right for your configuration, so probably just an extraneous detail from his/her config file. Obviously, if I missed something about your configuration and you do need it there, then go for insertProviderAt().
除非提供者的顺序对您来说很重要，否则只需使用 addProvider() 。我看到一位贡献者评论说您可能会将它插入到条目 #9，但我没有看到证据表明这适合您的配置，所以可能只是他/她的配置文件中的一个无关紧要的细节。显然，如果我遗漏了有关您的配置的某些内容而您确实需要它，那么请使用 insertProviderAt()。
