简单几步让网站支持https，windows iis下https配置方式

1.https证书的分类

SSL证书没有所谓的"品质"和"等级"之分，只有三种不同的类型。
SSL证书需要向国际公认的证书证书认证机构（简称CA，Certificate Authority）申请。
CA机构颁发的证书有3种类型：
域名型SSL证书（DV SSL）：信任等级普通，只需验证网站的真实性便可颁发证书保护网站；
企业型SSL证书（OV SSL）：信任等级强，须要验证企业的身份，审核严格，安全性更高；
增强型SSL证书（EV SSL）：信任等级最高，一般用于银行证券等金融机构，审核严格，安全性最高，同时可以激活绿色网址栏。

我们只要使用DV证书就可以了，一般来说我们申请到的免费ssl证书都是dv证书。

2.申请免费的证书

2.1 自签名惹的祸

Ca证书必须要可信任的机构颁发才可以信任，自签名证书就是自己给自己签名，没有通过第三方CA机构颁发。浏览器默认添加了一些可信任的CA机构，都是通过国际Web Trust认证的。

如果你的CA证书不是这些浏览器里默认添加的可信任的CA机构签发的话，那么就会出现像12306这样的笑话。

2.2申请免费的DV证书

Let's Encrypt是国外一个公共的免费SSL项目，由 Linux 基金会托管，由Mozilla、思科、Akamai、IdenTrust和EFF等组织发起，靠谱！

申请免费的证书可以参考这篇文章，工具和步骤都非常的完整，这里就不累述了

http://www.cnblogs.com/teamblog/p/6219204.html

最后申请完之后iis的配置就是新建一个网站，其他都不用配置，就可以了，老的网站不要删除，如果要强制https访问的话可以再搜索其他的文章，这里不再展开

3.https网站安全验证

https已经可以访问了，但是https就一定是安全的吗，我们可以通过下面这个网站进一步检查你的网站的安全性，主要是从https的安全性去测试

https://www.ssllabs.com/ssltest/analyze.html

可能一开始测试是个F，像我一开始测试就是个F，这是因为操作系统的默认设置里有很多不安全的设置，需要我们手动来配置修改。

可以仔细看下面的说明，没有开启TLS1.2 ，RC4已经过时了，Forward Secrecy支持的不好等等。

4.为了A+不断修改

这里大段的删除线是我一下午的心血，哪怕最后发现了powerShell脚本可以一次性完成上面所有的工作，你可以不看，但请尊重我的劳动

4.1 关闭SLL2和SSL3

找到HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols右键->新建->项->新建SSL 2.0，SSL 3.0
SSL 2.0和SSL 3.0 中间是有空格的！！！

在SSL 2.0 和 SSL 3.0上分别右键->新建->项->新建Server, Client
在新建的Server和Client中都新建如下的项(DWORD 32位值),

DisabledByDefault 值1

Enabled 值0

总共8个

、

4.2 开启TLS1.0 1.1 1.2

还是在刚才的目录下面，新建3个TLS 1.0 ，TLS 1.1，TLS 1.2

然后分别在下面建立Client，Server

然后跟一样在每个里面建立下面的项(DWORD 32位值)

DisabledByDefault 值 0

Enabled 值1

图都一样，就不重复截图了

完成上面的步骤后重启服务器就可以看到效果了

4.3 关闭RC4

这里的步骤更复杂，但和上面大同小异 ，无非就是在注册表里创建项，设置键值。

但是做到这里，我发现最后一步的powerShell脚本把所有的事都做了。所以后面的步骤我们都省略吧！！！！！！！！

4.5 修改ssl配置设置

别的我就说，在这个ssl配置的时候我尝试了很多种Cipher Suites的配置方式，包括参考别人A+的网站上报告里的配置，一个一个复制出来，每次都要重启服务器，重新测试，花了好多时间，最后终于评价成为A-，剩下一个Forward Secrecy的问题，结果搜索到一份powershell的脚本，问题是一步一步处理的，没毛病，但最后找到一个脚本一次性解决了前面所有的问题，所以分享出来给大家，减少大家走弯路的时间

4.6 最后配置 Forward Secrecy

4.7 一键配置的powershell脚本

Powershell脚本原文：

https://www.hass.de/content/setup-your-iis-ssl-perfect-forward-secrecy-and-tls-12

使用方法是，开始-》运行-》输入powershell，打开类似cmd窗口的命令行工具，然后直接复制脚本进去执行就ok了。
