NGINX不支持tls1.2密码

问题描述

我想在nginx（v1.16.1）中添加一些TLS 1.2密码，而其中只有2个有效。

下面是我想得到支持的密码列表。

DHE-RSA-AES128-GCM-SHA256;

ECDHE-RSA-AES128-GCM-SHA256; ->可行

DHE-RSA-AES256-GCM-SHA384;

ECDHE-RSA-AES256-GCM-SHA384; ->可行

ECDHE-ECDSA-AES256-GCM-SHA384;

默认情况下添加在以下行中。conf

server {

    ssl_protocols TLSv1.2;
    ssl_prefer_server_ciphers off;
    ssl_ciphers "DHE-RSA-AES128-GCM-SHA256 ECDHE-RSA-AES128-GCM-SHA256 DHE-RSA-AES256-GCM-SHA384 ECDHE-RSA-AES256-GCM-SHA384 ECDHE-ECDSA-AES256-GCM-SHA384";

...
}

我正在使用open ssl命令对其进行测试

openssl s_client -cipher DHE-RSA-AES128-GCM-SHA256 -connect localhost:8443  -tls1_2
openssl s_client -cipher ECDHE-RSA-AES128-GCM-SHA256 -connect localhost:8443  -tls1_2
openssl s_client -cipher DHE-RSA-AES256-GCM-SHA384 -connect localhost:8443  -tls1_2
openssl s_client -cipher ECDHE-RSA-AES256-GCM-SHA384 -connect localhost:8443  -tls1_2
openssl s_client -cipher ECDHE-ECDSA-AES256-GCM-SHA384 -connect localhost:8443  -tls1_2

一件被标记的作品使结果保持静止，如下所示

openssl s_client -cipher DHE-RSA-AES128-GCM-SHA256 -connect localhost:8443  -tls1_2

我的配置是否有问题或不支持密码？

解决方法

对于Diffie Hellman密钥交换，您需要为nginx提供dhparam：

openssl dhparam -out /etc/ssl/certsdhparam.pem 4096

并在nginx conf中进行配置：

ssl_dhparam /etc/ssl/certs/dhparam.pem;

请参见reference

对于ECDHE-ECDSA-AES256-GCM-SHA384;，您还需要使用ecdsa密钥和证书。参见guide

混合RSA和ECDSA证书示例配置：

ssl_certificate /path/to/rsa.crt;
ssl_certificate_key /path/to/rsa.key;
ssl_certificate /path/to/ecdsa.crt;
ssl_certificate_key /path/to/ecdsa.key;

请参见reference
