独立博客 DV SSL 证书推荐，三年 15 刀

根据 1 楼的提示，去查看了 Namecheap，的确有这么个活动，想折腾的可以去试试，反正又不花钱，但是搞不懂那个验证级别到底依据是啥，也就是如果你注册了 namecheap 后，最终到底有效期是 24 个月还是 36 个月目前不确定。像我一样不想折腾的可以直接买，一张毛爷爷用三年 COMODO DV SSL 也值了！
==============================官方活动示例说明=============================
For example, let ’ s say you bought a single domain Symantec SSL for your online shop through another provider. It expires in three months. By signing up with Namecheap now, you can replace that SSL with a Comodo SSL for those remaining three months for no additional cost or obligation.

Once you sign up, Comodo will issue your site a new certificate for 24 or 36 months, depending on the level of validation. At the end of the free period, you can choose to extend your SSL. And don ’ t worry, we ’ ll send you a reminder email with the option to extend. At that point, you can choose to extend for one year or to the end of the certificate period, or, if you wish, you can let the certificate expire with no further obligation.

大概意思是，你已经有赛门铁克的证书后，可以通过 1 楼提供的地址，去申请一个免费的 COMODO 证书，证书类型和你已经在用的赛门铁克证书一致，有效期为你赛门铁克证书的剩余时间。注意！注意！还没有结束，如果你这时候注册登录了 namecheap 网站，将根据你的验证级别（目前不知道具体的依据是啥）为你的站点新颁发一个 COMODO 的 SSL 证书（有效期为 24 个月或者 36 个月），证书的有效时间取决于上面提到的验证级别。
