Generate cert.pem and key.pem on Windows

I need to generate a cert.pem and key.pem files to encrypt http requests with Nginx.

On Linux, I would execute the following OpenSSL command:

openssl req -x509 -newkey rsa:4096 -nodes \
          -out ./nginx/config/cert.pem \
          -keyout ./nginx/config/key.pem -days 365

What would be an equivalent command to generate such files on Windows? I have followed this guide but it only generates a .crt and .key files instead.

  • Collecting answers from the comments above:

    If you install openssl onto windows then it's the same command.

    Or

    Rename privateKey.key to key.pem and certificate.crt to cert.pem. It should work just fine

    Or

    I have also created an OpenSSL Docker container which allows to generate certificates without needing to install OpenSSL on Windows or Linux (assuming you have Docker already installed): https://github.com/alexisrolland/docker-openssl
