创建自签名 SSL 证书 - nginx

我想为我的网站创建一个自签名 SSL 证书。我不会使用它来访问网站本身，而是使用它来访问我将要使用的其他服务（roundcube、phpmyadmin 等）。我想在这些服务中使用 https，因为我将与服务器交换敏感数据。所以我需要我的虚拟主机所需的密钥和证书。

我的问题是生成它的正确方法是什么。我对不同的后缀 crt、pem、key 感到困惑，我在互联网上找到了很多不同的方法。我使用的 Web 服务器是 nginx。

另外密钥可以有多长？可以长于 4096 位吗？

谢谢

这是一个简单易用的简单示例:)

sudo mkdir /etc/nginx/ssl
cd /etc/nginx/ssl
sudo openssl genrsa -des3 -out server.key 1024
sudo openssl req -new -key server.key -out server.csr

into your certificate request.
What you are about to enter is what is called a Distinguished Name or a DN.
There are quite a few fields but you can leave some blank
For some fields there will be a default value,
If you enter '.', the field will be left blank.

sudo cp server.key server.key.org
sudo openssl rsa -in server.key.org -out server.key
sudo openssl x509 -req -days 365 -in server.csr -signkey server.key -out server.crt

# HTTPS server

server {
        listen 443;
        server_name example.com;

        root /usr/share/nginx/www;
        index index.html index.htm;

        ssl on;
        ssl_certificate /etc/nginx/ssl/server.crt;
        ssl_certificate_key /etc/nginx/ssl/server.key; 
}
