To provide higher security and better privacy protection, I added SSL certificate on my Blog, here.
When you enter the url of my blog: http:///www.yinfor.com/, it will redirect you to the SSL version, https://www.yinfor.com/
The certificate is purchased from gogetssl.com , three years certificate of Comodo PositiveSSL.
The latest price is $13.15/3years.
Look at the comodo secure lock, it is a site seal.
