使用Bouncy Castle Java API生成X.509证书

我正在尝试使用Bouncy Castle Java API生成一个X.509证书

我在以下位置找到了示例代码：

但是，在编译下面的代码之后，JVM会显示一条错误消息，如下所示

找不到主类：org.bounchycastle.util.AllTests。程序将退出。

注意，

org.bounchycastle.util.AllTests

被插入到Java构建路径中

如何修复代码以使其正常工作

您可能应该在类路径中包含bctest-jdk15on-147.jar（）

AllTests不在类路径上。这不是一个类路径问题，AllTests类已经在类路径上了，这是您没有得到的。错误告诉您它不在类路径上。这意味着它不是，故事的结尾。
