Acme-TinyTLS 证书加密工具
Acme-Tiny 是采用Python编写的，一款轻量级的TLS 证书加密工具。
使用
获取秘钥
openssl genrsa 4096 > account.key
使用现有的秘钥

创建证书签名请求 (CSR) 的域名

关联到网站主机
#example for nginx
server {
listen 80;
server_name yoursite.com www.yoursite.com;
location /.well-known/acme-challenge/ {
alias /var/www/challenges/;
try_files $uri =404;
}
...the rest of your config
}
获取签名证书
#run the script on your server python acme_tiny.py --account-key ./account.key --csr ./domain.csr --acme-dir /var/www/challenges/ > ./signed.crt
安装证书
server {
listen 443;
server_name yoursite.com, www.yoursite.com;
ssl on;
