Right.

If i am not terribly mistaken there's no way to revoke a certificate that is in 
a CA hierarchy with the system keyring on top of it.  Certain scenarios require 
us to revoke them as it was presented at the last year's LSS.

If x509_key_preparse() is not the right place then where shall i place the 
check?
