💰退款遇到的问题
✋ 有个别客户遇到,原因是秘钥太长导致
java中使用AES对称加密后,请求报错: Caused by: java.lang.RuntimeException: java.security.InvalidKeyException: Illegal key size or default parameters at com.
原因是美国的出口限制,Sun通过权限文件(local_policy.jar、US_export_policy.jar)做了相应限制。密钥长度最大128,对于需要更大长度的场景则会抛出上面异常。

✅ 解决办法是下载Oracle官方网站上的无政策限制权限文件,下载链接:
jdk8:https://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html
✅ 也可以通过我准备的网盘下载-快不用注册Oracle

🚗 下载后将%JAVA_HOME%\jre\lib\security
中的local_policy.jar
和US_export_policy.jar
替换为下载包中的的local_policy.jar
和US_export_policy.jar
。
在CentOs 7.6环境查看jdk安装目录
在/usr/java/jdk1.8.0_131/jre/lib/security下替换local_policy.jar和US_export_policy.jar
tips 官方的密钥应该再128之内
