命令行输出的错误信息：

第一个browser中报的错我分析是权限问题，第二个在shell中运行才是其真正的问题所在，根据提示，使用brew安装gpg-agent。
之后我编写代码如下：
require_once'./crypt/gpg.php';$gpg = new crypt_gpg();$key = getkey();$gpg->adddecryptkey('zhangsanfeng','123456');$encrypted = file_get_contents('wait_for_decrpyt.txt.gpg');$data = $gpg->decrypt($encrypted);echo''
;var_dump($data);exit;终于解密成功！！！
