You don't create it. See above. If you understand what is is you know
why it can't be builtin. If you don't understand it is better if you
first learn about OpenSSL, otherwise you run the risk to make serious

If you are just experimenting to create a message for yourself then you
have to create the public key because you are then the recipient
yourself. That has been answered on
