A#) openssl req -x509 -nodes -newkey rsa:4096 -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 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, 'You can set an empty issuer/subject DN, or use "-keyid" to avoid copying these into the CMS message.' Can someone please update my included A#), B#) or C#) instructions, included above here, to acheive this suggestion, so that no certificate information is put into 'encrypted.dat', including the nation, so that 'encrypted.dat' includes no plain text whatsoever, and so that A#) + B#) + C#) all work as desired, for small, medium and large files, of 'message.txt'? I am struggling to correct what I have done so far, so that there are no errors, and so that all the steps work: (generation of a private and public key, encryption of the file, and decrypt of the file). ?
