用CMD命令行运行.jar时出现如下错误，解决办法如下：

F:\ChromDownload\RSA签名验签工具windows_V1.4>java -jar openssl_tools.jar
Exception in thread "main" java.lang.reflect.InvocationTargetException

解决方法
F:\ChromDownload\RSA签名验签工具windows_V1.4>jre\bin\java.exe -jar openssl_tools.jar

个人认为出现上面错误并不全是jdk版本的问题，应该是其中的某一个地方错误，所以按照其他的方法我成功运行了此jar包，
