Revoke certificates

   
   1. Re-key your server. This means creating a new RSA or DSA server key, 
creating a new CSR for your Certificate Authority, and applying for a 
replacement certificate. All CAs allow for the revocation of a server 
certificate due to “key compromise” which is exactly the reason for the 
re-keying of your server. You should be able to obtain a replacement 
certificate at no charge, though free-certificate providers may charge a fee 
for revocation/replacement.
  
+  1. Revoke any certificates that might have been compromised.
+ This does not guarantee that the old certificate cannot still be used in MITM 
attacks, as most browsers don't check revocations in a timely fashion (if at 
all).
+ However it should help to catch some attacks.

  Yes: you need to change any password that ever traversed your HTTP server 
while vulnerable. That pretty much means you have to change all passwords, and 
notify your users that they should change all their passwords as well. 
Unfortunately, any other sensitive information that traversed your server 
should be consider compromised. In many cases, there is nothing to be done 
unless that information can be changed (credit card numbers, account numbers, 
passwords etc.).
