Bluehost主机提供免费共享SSL证书，怎么用呢？美国Bluehost官网原文教程如下：
How can I use my website with the Free SSL Certificate?
To use the shared SSL Certificate, update the hyperlinks that need to be secure to use the base URL of:
https://box###.BlueHost.com/~username
美国官网bluehost优惠链接。
In the above example replace box### with the server for your account. You can find that on the left side of your cPanel in the stats column. Also replace “username” with your 8-character cPanel username. This also is listed on the left side of your Bluehost cPanel.
Please note the Shared SSL Certificate does have data limitations; in order to prevent abuse by others using the free secure.BlueHost.com SSL proxy, any embedded data (images, audio clips, etc) larger than 100kb will be truncated; this is a per-file limit, not a total page size limitation. This can cause elements on your websites to only load half-way, especially on those websites using larger images.
从上面的教程可以看出这个免费的SSL其实没有什么用，网站要使用SSL证书还是要买付费的SSL证书，一般虚拟主机直接在bluehost购买商用SSL即可。当然，要能够使用SSL证书，还得先买一个独立IP。当然，SSL证书在任何一家主机商都是需要独立IP的。
以上是bluehost英文官网的SSL介绍。如果想了解bluehost中文官网SSL的介绍请进入Bluehost中文官网，地址是http://cn.bluehost.com。Bluehost中文官网所售bluehost主机与bluehost美国官网所售主机方案和配置均不尽相同，但技术和美国官网所售主机相同，所以，用户也可在bluehost中文官网购买bluehost主机。bluehost中文官网机房可选择范围比其英文官网的数量多，不仅有美国机房，还有香港机房、欧洲机房、印度机房，也有上海机房，不过上海机房和其它机房不同，在bluehost中文官网http://cn.bluehost.com点开上海机房链接后会发现地址是bluehost.cn。
