Exporting a Certificate as BASE-64 encoded .cer

Question

I am trying to export a cert without the private key as as BASE-64 encoded file, same as exporting it from windows. When exported from windows I am able to open the .cer fil

Answer 1

//however, missing the "-----BEGIN CERTIFICATE-----" and "-----END CERTIFICATE-----"

These missing lines are optional. CA may generate them or not depending on settings. For all practical reasons they can be removed from the Base64 encoded file.
