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X.509证书。
我找到了示例代码：
http://www.bouncycastle.org/wiki/display/JA1/X.509+Public+Key+Certificate+and+Certification+Request+Generation
但是，在编译以下代码之后，JVM会显示错误消息，如下所示
Could not find the main class: org.bouncycastle.util.AllTests. Program will exit.
请注意， org.bouncycastle.util.AllTests将插入到Java构建路径中。
如何修复我的代码才能正常工作？

您应该在类路径中包含bctest-jdk15on-147.jar（ http://www.bouncycastle.org/download/bctest-jdk15on-147.jar ）。
