NGINX不支持TLS1.2密码

Question

DHE-RSA-AES128-GCM-SHA256；

ECDHE-RSA-AES128-GCM-SHA256；-->这管用

DHE-RSA-AES256-GCM-SHA384；

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";

是我的配置有问题还是密码不受支持。

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中配置它：

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

参见参考资料

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;
