使用CryptoRandomFactory类的getCryptoRandom方法时获取异常 Apache-公共密码库

问题描述

我正在尝试使用Apache Commons Crypto库。我正在使用来自Apache官方站点的示例代码来使用此库的Random API。 这是指向它的链接-https://commons.apache.org/proper/commons-crypto/xref-test/org/apache/commons/crypto/examples/RandomExample.html

使用方法getCryptoRandom时出现此异常。

以退出代码1完成的过程

如何解决此问题？

据我了解，问题在于加载openSSL引擎或类似的东西：
