Question

在www.ssllabs.com上测试我的SSL证书时，我试图在所有类别上获得100分

然而，我很难在所有分数上获得A +和100分。

有关NGINX配置我应该使用的任何提示吗？或者我应该如何生成我的Let的加密证书？ THX

Answer 1

这些说明适用于所有证书（包括Let's Encrypt证书）。但是，我们会给出一两个Let的特定提示。

下面给出的NGINX SSL配置将为您提供以下SSL Labs分数。你选择：

<强>推荐

A +
证书100/100
协议支持95/100
密钥交换90/100
密码强度90/100

完美但限制性

A +
证书100/100
协议支持100/100
密钥交换100/100
密码强度100/100

NGINX SSL配置 - 提取您想要的位数。这些说明澄清了给定的NGINX指令将如何影响您的SSL Labs得分：

# Your listen directive should be .. listen 443 ssl http2;
# gzip off; # gzip over ssl? really?

ssl_certificate      /etc/letsencrypt/live/yourdomain.com/fullchain.pem;
ssl_certificate_key  /etc/letsencrypt/live/yourdomain.com/privkey.pem;

注意，如果你的：

，你只能在密钥交换上获得100

证书RSA密钥大小为4096（对于Let＆＃39的加密，在生成证书时使用--rsa-key-size 4096，否则您将无法使用CA为您生成证书时使用的RSA密钥大小）和
dhparam是4096（openssl dhparam -out dhparam4096.pem 4096） - 这需要大约1个小时来生成，对于自动化解决方案毫无用处

修改

2048年的安全性足以满足未来40年的需求。没有人破解1024，更不用说2048了！

openssl dhparam -dsaparam -out dhparam4096.pem 4096 ...比一小时快得多（参见-dsaparam旗）但我不知道你是否应该使用它...我没有在SSL实验室测试中测试过，因为我正在使用2048

你如何使用Let's Encrypt和Nginx在SSL实验室测试的所有类别中获得A + 100分？
