<p>I am wondering if calling JSON-RPC from the computer it is running on is secure. I read <a href="https://bitcoin.stackexchange.com/questions/2651/how-secure-is-calling-bitcoind-json-rpc">How secure is calling bitcoind JSON-RPC?</a> and understand why it is insecure to do so from a different computer.</p>

<p>Is there a secure way to call it from the same computer <strong>without</strong> using <a href="http://en.bitcoin.it/wiki/Enabling_SSL_on_original_client_daemon%20p" rel="nofollow">SSL?</a></p>

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.

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?](https://bitcoin.stackexchange.com/questions/2651/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?](http://en.bitcoin.it/wiki/Enabling_SSL_on_original_client_daemon%20p)
