gpg加解密異常

 

在本地windows電腦和開發環境(linux) ，都不報錯，但是在測試環境(linux) 上報錯。

原因：

  默認自帶的policy.jar不支持gpg加密的功能。 需要替換jar 

方法1：  修改java.security

先找到java的安裝位置

windows下查看版本：（默認安裝路徑安裝就不需要去配環境變量了）

1 java -version

windows下查看安裝路徑：

1 java -verbose

 

找到 jre/lib/security/java.security

檢查是否有寫入的權限爲（644）沒有的話授權

vi  jre/lib/security/java.security

新增

security.provider.10=org.bouncycastle.jce.provider.BouncyCastleProvider

 

保存完成在把文件的權限改爲(444)

 

2、方法2

  替換

jre/lib/security/policy/limited/local_policy.jar
jre/lib/security/policy/limited/US_export_policy.jar

並修改爲權限（644）
