Securing password between webserver & appserver.

[Chintan Oza <chintan.oza () gmail com>]

Dear All,

We have a web application which perform user authentication on
id+password basis.

The architecture is like this.
Browser<-HTTPS->WebServer<-->AppServer

We have a requirement where password should not be available to the
WebServer (even in hashed format).

Only solution that I can think of is having an Applet performing PKI
encryption on the password before submitting the form.

Please suggest if there are any better alternatives.

Thanks,

Chintan
