You have generated certificate requests and key pairs.
It is strongly recommended that you back up your Enrollment Key Pairs. This will serve to verify that keys were generated and that you are in possession of the passwords assigned to protect these key pairs. Additionally, if you put the back-up files on external media (CD, thumb drive, etc.), this will mitigate the risk of technical problems destroying your certificates.
You can find instructions for backing up your enrollment keys here:
Once you have successfully made back-up files of your Enrollment keys, you can take your request forms to the Notary.
