I think this is a reference to the action historically called "form signing"
(or more accurately "form post signing") in Mozilla.  It's a way to sign the
data being sent in to a web server with the user's private key, as the data
is being sent.  Mozilla implements this with a javascript extension known
as "crypto.signtext".  I think IE implements it with an ocx (an Active-X
module).  There doesn't seem to be any standard for a way make this work
that is common to all browsers.   NSS provides the necessary crypto code.
What's missing is the definition of the way (syntax) by which to invoke it
in the browser.  If I recall correctly, Anders has proposed something for
that purpose, and perhaps he has developed some software for that purpose.

There are some fundamental issues with this stuff, such as, how does the
user know what he's being asked to sign?  How does he know that he's not
being asked to sign a document conveying the deeds for all his real property
to the web site owner? In some countries where digital signatures have the
full force of law, just like a real signature, this could be a serious issue.
I'm personally wary of efforts that push to make it possible for users to
make such legally effective signatures without solving the problems of how
to protect the user.
