ssl.SSLError: [SSL: EE_KEY_TOO_SMALL] ee key too small

我的web server 顯示錯誤訊息:

File "/usr/local/lib/python3.8/dist-packages/tornado/netutil.py", line 576, in ssl_options_to_context
        context.load_cert_chain(
    ssl.SSLError: [SSL: EE_KEY_TOO_SMALL] ee key too small (_ssl.c:4046)

解法,透過下面的指令來建立私有的憑證

openssl req -x509 -nodes -days 365 -newkey rsa:2048 -keyout server.key -out server.pem

You are right, increase your rsa to 2048, this will solve your problem.
