Thanks Michael!!

I will read this RFC and get more details.

But I have one more question: When my client (in his browser) generate a 
certificate and change the key pair, install the certificate and will use it 
with the same browser configuration, the certificate works.

But if the client that have one cert installed change the browser options 
(level of security, uses of SSL 2, SSL 3 or TLS, or aplly the windows patch 
Q323172 (responsable for a vulnerability with certs) the certificate stop 
working and we have to tell to the client make a new certificate to work with 
the new configuration.

So, my question is: In the moment of the change key pair/generate, the 
certificate get some information about browser's configuration? Get any state 
of the selected SSL option or browser security level?

Please, If someone have any document wich explain what exactally happen in this 
moment tell me!

Thanks,
Andr�a
