What I advise is to look at the code defining `read-passwd', and define your
function similarly.
What you see there is that `read-key' is called and each key that is read is
handled with a case analysis. What you want is to add another case (or cases).
See how that code currently handles special lists of keys: `stop-keys' and
`rubout-keys'. More pertinent perhaps is the treatment of `C-y'.
HTH.
