  SOMEBODY has to tell the world to revoke the cert.  If YOU
weren't DEAD, you could do it...

Isn't that something you would put in your will and require 
be executed? 

If you're this paranoid you could require two unrelated 
parties do it together.

Thanks tracy. In the event that i die, what stops someone 
with access to my digital certification pose as me? Does 
someone have to revoke MY certificate in the even of my death?

Regards

Munya

spake thusly:
Another question from yours truly. When someone has a digital 
certificate, and then passes away (dies) how does the Revocation 
authority get to know about this so as to disallow further use of 
that persons digital cert?

The authority needs to be sent a revocation request signed by the 
certificate being revoked. It is good practice to generate this 
revocation request at key generation time and keep it in a 
safe place. 
This is because if the signing key is lost such that no signed 
revocation certificate can be generated it becomes impossible to 
revoke.

Similarly, if the private signing key is encrypted and the owner of 
the key takes the password to their grave it is impossible 
to generate 
a revocation certificate.
