Question

我正在尝试使用Mule对PGP进行加密，但我收到的“publicKey不应为null”错误。

我在这里替换了local_policy.jar和US_export_policy.jar：C：\ Program Files \ Java \ jdk1.7.0_45 \ jre \ lib \ security

在我的图书馆中我有：bcpg-jdk15on-150.jar。我还添加了local_policy.jar（不确定我是否需要它，但我尝试使用和不使用并得到相同的错误）。

我正在运行MuleStudio 3.5和CE-3.4运行时。

Answer 1

由于您使用的是MuleHeaderCredentialsAccessor并且尚未设置标头MULE_USER，或者它被设置为与密钥环中的任何uid都不匹配的值，因此会发生异常。

您必须设置此标头（入站属性）或实现自己的CredentialsAccessor，以返回正确的凭据。

您可以找到MuleHeaderCredentialsAccessor的代码，在this page上可以找到一个返回硬编码凭据的简单示例CredentialsAccessor。

Answer 2

我得到了解决。请检查credentialAccessor的{{1}}值以及导入的pgp密钥集。简单的方法是调试方法credentials上的org.mule.module.pgp.KeyBasedEncryptionStrategy行private PGPCryptInfo safeGetCryptInfo(Object cryptInfo)将为您导入的密钥及其凭据来自您导入的流和密钥。

尝试在Mule中进行PGP加密时，publicKey不应为null
