Node.js Open SSL Helper with LetsEncrypt Support

Tool to assist with creating a CA using Open SSL as well as adding support for requesting lets Encrypt certificates

Tested on openSLL 3.0.1

Example of creating a CA key and Cert then creating client, webserver, CRS and Certificate

Open and Debug examples/basic/basic.js using visual Code.
