前言
2017年1月1日起App Store上的所有App应用将强制开启ATS功能。 苹果的ATS(App Transport Security)对服务器硬性3点要求： ① ATS要求TLS1.2或者更高，TLS 是 SSL 新的别称。 ② 通讯中的加密套件配置要求支持列出的正向保密。 ③ 数字证书必须使用sha256或者更高级的签名哈希算法，并且保证密钥是2048位及以上的RSA密钥或者256位及以上的ECC密钥。
由于领导舍不得花钱，只能辛苦我们自己搞个不花钱的证书。在网上找了一大堆各种配置证书服务的文章，在ios端运行的时候总是直接报错，很是费解，后来注意到必须是TLS1.2或者更高的版本，而按照网上的配置弄好后都是ssl1.0，根本原因没有解决。所以必须先升级服务器ssl的版本，这个升级的文章很多，有用的不多。在这里整理下找到的资料，供大家参考。注意：证书服务可以不用安装，升级ssl后即可正常访问。
1.首先打开服务器组策略，命令行输入gpedit.msc，找到ssl配置设置，双击ssl密码套件顺序，选择已启用，并保存。准备工作完成！
2.在下面选择您需要的配置并复制，打开Powershell直接粘贴。最后会提示是否重启服务器，输入Y会直接重启，根据自己的情况而定吧，重启后生效哦~

3.最后配置IIS站点，添加ssl自签名证书，站点绑定https，并选择刚添加的自签名证书即可。
4.全程无需给服务器安装证书服务，ios客户端证书校验时默认全部通过即可，如果对安全要求严格的客户端可导入证书做校验。
