How to generate a certificate signing request

Below are brief descriptions of what may be requested during this process. Anything that is in bold must be filled in exactly as given right down to the capitals.

Note that the information you include in the certificate request must be exact and correct. Some data names are misleading. If you are not 100% sure of how to fill in a blank during this process please ask us as it will save a lot of time later. Note that the key must be kept safe as if it gets into public hands then all encryption efforts are lost and your system can be spoofed by others.
