2. Navigate to the OpenSSL bin directory.
   • c:\OpenSSL\bin\ in our example.
3. Right-click the openssl.exe file and select Run as administrator.
4. Enter the following command to begin generating a certificate and private key:
   • req -x509 -sha256 -nodes -days 365 -newkey rsa:2048 -keyout privateKey.key -out certificate.crt
5. You will then be prompted to enter applicable Distinguished Name (DN) information, totaling seven fields:
   
6. Once completed, you will find the certificate.crt and privateKey.key files created under the \OpenSSL\bin\ directory.

Congratulations, you now have a private key and self-signed certificate!
