在Grails 2.5.0中找不到BouncyCastleProvider类

Question

我有一个Grails项目，我想在其中使用Bouncycastle来计算字符串的Sha512哈希值。

当我致电Security.addProvider(new BouncyCastleProvider())时，收到以下错误消息：

| Error 2015-06-21 15:34:53,242 [localhost-startStop-1] ERROR context.GrailsContextLoaderListener  - Error initializing the application: org/bouncycastle/jce/provider/BouncyCastleProvider

在我的IDE（IntelliJ）中，导入import org.bouncycastle.jce.provider.BouncyCastleProvider似乎已解决，我可以导航到该类的位置。

为什么执行应用程序时找不到BouncyCastle类？

Answer 1

您是否在正在使用的JRE的JCE安全策略文件中添加了提供程序的条目？

JAVA_HOME\jre\lib\security\java.security

n比已存在的最后一个条目多一个

security.provider.n=org.bouncycastle.jce.provider.BouncyCastleProvider
