Q: How do I know if I’m using an affected certificate?
A: Here is an online tool that will show you: 
https://checkhost.unboundtest.com/ 1.8k

Or, on a Linux/BSD-like system, this command will show you example.com's 
current certificate serial number:

openssl s_client -connect example.com:443 -servername example.com -showcerts 
</dev/null 2>/dev/null | openssl x509 -text -noout | grep -A 1 Serial\ Number | 
tr -d :

You can see the list of all affected serial numbers at:
