Illegal base64 character 2d 问题已解决

-f 参数要使用：apiclient_key.pem

但是又出现了新问题
java.security.InvalidKeyException: Illegal key size

java.security.InvalidKeyException: Illegal key size 问题已解决

由于jdk限制策略，导致只能128位key进行加解密，而256位加解密则抛出异常。

Oracle 为我们准备了替换的Jar
将local_policy.jar和US_export_policy.jar 两个Jar包，替换到： jdk目录/jre/lib/security/ 目录下
