Hide sensetive data during input creation

[mstoro]

Hi, I've built the add-on using Add-on Builder which gathers some data from user including an API key (type o f the field is password so it replaces API key with asterisks on the input creation page).
During the creation of an input I can see that the API key is not encrypted an passed to new_input request as a plain text in the payload body. It only happens if the API key is valid.

Is there any way to remove or hide the API key there?

@mstoro - I believe this should not be encrypted in the browser. It will be encrypted on the fly if you are using Splunk UI on HTTPS.
