[En-Nut-Discussion] Web page security?

[Tim Tait]

I gave a couple of questions on security of the ethernut web 
authorization (as shown in the httpd sample app), as I am planning on 
using for some home automation tasks.

- Are passwords encrypted on the wire?
- If so by what means?
- Are replay attacks possible?

I read some stuff about TEA (Tiny Encryption Algorithm) 
<http://www.ftp.cl.cam.ac.uk/ftp/papers/djw-rmn/djw-rmn-tea.html>, has 
anybody used it with NutOs/NutNet to secure web pages or telnet?

Thanks-

Tim
