Your issue description goes here below. Try to include actual vs. expected behavior and steps to reproduce the issue.

I am attaching Parity JS shell to a node using SSH tunnel. After entering my signer password I am asked to "Select Local Key" and enter a password. I thought this was the UTC private key file but when I upload that file and add the password I get the error:

Signing and Decrypting with JSON file is not supported for now

What file is the Shell expecting me to upload?
