项目中加密算法时报错:Illegal key size or default parameters  
在java中可能会面临需要加密 解密传输一些数据信息, 最近我就在项目中用到加密算法AES, 然而在启动项目时,给我报错了

经过查阅资料

发现 我们jdk 或jre\\lib\\security目录 下, 需要两个保密的jar文件  
 Oracle在其官方网站上提供了无政策限制权限文件（Unlimited Strength Jurisdiction Policy Files），我们只需要将其部署在JRE环境中，就可以解决限制问题。

把里面的两个jar包：local\_policy.jar 和 US\_export\_policy.jar 替换掉原来安装目录jdk中或者jre中的\\lib\\security 下的两个jar包接可以了
