Nothing new here, just another personal note on how to do something so I don’t forget.
Generate a new private key and Certificate Signing Request
openssl req -out CSR.csr -new -newkey rsa:2048 -nodes -keyout privateKey.key
To export the private key without a passphrase or password
openssl pkcs12 -in filename.pfx -nocerts -nodes -out key.pem
To Generate a public version of the private RSAkey
openssl rsa -in key.pem -out server.key
To export the Certificate
openssl pkcs12 -in filename.pfx -clcerts -nokeys -out cert.pem
The directory will now have a file cert.pem and a key.pem
