Hi All,

I am in fact newbie to Google gadget development and planning to
develop a gadget that requires user to login.  In this regards, I have
some security issues in the implementation.

1.  I understand google gadget comes in two types:  a)  content type =
html &  b) content type =url.  For gadget that requires login, it is
recommended to use version b) <i.e. content type=url> according to the
doc.  While it is true that I can specify a secured https link for
gadget content with type url, is there anyway for gadget user to
access/add the gadget specification (i.e. the gadget xml file) using
https as well?  If not, it seems that I can only ensure the data being
input is interacting with a trusted source but not the gadget
specification (i.e. the gadget xml file).  In particular, I am afraid
case B described below will happen.  Scenario as follows:-

A)  Web Client -->  Gadget Spec (xml file)  - [content type= url:
https://trusted site] ->  Trusted Site
B)  Web Client -->  Phishing Gadget Spec (evil xml file) -> Stealing
Sensitive Information -> redirect back to the trusted site

2.  For normal https site, user can see the certificate information
and the "lock" logo from the browser, is there a way for gadget to
show this information to user as well to ensure user is browsing a
trusted site?

3.  Is there any other security issues that I need to pay attention if
I want to develop a secure gadget?

Thanks a lot in advance.

Best Regards,
kaiphone
