Java 创建密码时出现BouncyCastle异常

我试图在我的tomcat本地运行一个项目，但是我从BouncyCastle中得到一个异常

我已经检查了密钥的路径和密钥名，都是正确的。我还交换了jce策略文件。然而，问题仍然存在。还有什么建议吗

以下是整个例外：

您使用的是哪个版本的BouncyCastle？您尝试过使用SpongyCastle吗？在我的pom.xml中，我有以下BouncyCastle条目：BouncyCastle bcprov-jdk14 140和org.BouncyCastle bcpg-jdk14 1.47以下依赖项是否可能与我上面提到的exchange jce策略文件冲突？local_policy local_policy 1.0和US_export_policy US_export_policy 1.0考虑到您没有这样的算法异常，我猜您使用的是不兼容的BC版本。尝试其他版本。我尝试了其他版本，但仍然发生相同的异常。
