How to use openssl securely? I don't want openssl to log my keys and passwords... but I don't use gpg as I need more manual control for my purpose. I also don't like gpg  and would like to use openssl without logging.

Does openssl too engaging in logging when I open the interpreter


  Openssl


My main question revolves around linux logging when others have access to my offline pc?
If you are afraid that somebody can get access to your private keys or passwords, disconnect your machine from network and never connect it again; transfer public keys that you want to publish via USB stick; when you need to encrypt or decrypt something, use USB stick, put there the needed files, attach it to your offline machine, encrypt or decrypt on this machine, put result back to USB stick.

Depending on how important are purposes you use openssl for, you may want to put your machine in some room with proper electromagnetic and sound isolation :) And first of all, make sure nobody gets physical access to this machine :)
