Problem with Asymetric, two-key encryption and Certificate Requests.

I have wanted to get into public/private two key encryption, of
computer files of any type and any size and type. I am working on
Windows 10 64 bit.I found the ensuing approach by my own
experimenting, but it has a key disadvantage.
In order for the encryption step to work by means of the public key,
I have found the following approach with relies on the generation of a
Certificate Request. The problem is however, that by doing things like this,
A#) openssl req -x509 -nodes -newkey rsa:16384 -keyout private.key -out public.key
B#) openssl smime -encrypt -binary -aes-256-cbc -in message.txt -out encrypted.dat -outform DER public.key
C#) openssl smime -decrypt -in encrypted.dat -binary -inform DEM -inkey private.key -out decrypted.txt
I can get plain text injected into the encrypted text, which I want to totally avoid every part of.
How can I complete step A#), so that step B#) will work, without involving a Certificate Request, which requires
a non-blank two digit nation code, which gets put into the encrypted text in plain manner, a situation which
I want to do? How can I make A#) +B#) +C#) without certificate requests, without any nation code or plain text
injection into the encrypted text at all, for small, medium, large, any size and type of file?
