I am wondering if calling JSON-RPC from the computer it is running on is secure. I read How secure is calling bitcoind JSON-RPC? and understand why it is insecure to do so from a different computer.

Is there a secure way to call it from the same computer without using SSL?

  • It's secure in principle. Just make sure that if your doing this on a computer connected to the internet that all relevant ports are closed. Also there is not all the much of a point in using ssl on localhost, it will just add latency.

Yes. By default, Bitcoin will only listen for RPC connections on local loopback. Local loopback cannot be accessed or spied upon by another computer.
