This is an aside, but somewhat related.<p>Where are you suppose to store secretive environment variables like database password or apikey&#x2F;secret pair etc (say in Ubuntu server)? Is storing in something like ~&#x2F;.profile or ~&#x2F;.bashrc and doing `export SECRET_KEY=&#x27;plaintext_secret&#x27;` on the server enough, or should they be treated in an even more secretive manner?
