Answer 1

MSDN - How to create a custom field type

This topic provides an overview of the process of creating a custom field type and defining how it renders on list views and on the Display, New, and Edit forms.

For a concrete example of creating a custom field and defining its rendering, see Walkthrough: Creating a Custom Field Type.

The alternative 'hacky but pragmatic way' is as Vladi suggests using some Javascript (perhaps in a CEWP) to modify the pages HTML.

You would want to find the field INPUT tag and change the type to Password (this will then use * instead of chars).

This post gives you an walkthrough of opening up a New/Edit.asp form in edit mode, adding a CEWP that contains JavaScript and modifying the page. Its not exactly what you want but will get you started.

Answer 2

You can develop a custom field if you have the capability. Of course you can play around the replacing the HTML control in runtime using Javascript, but I would not recommend it
