As there are many clever IT boffins on here i thought id ask, essentially i need to secure my email to a client so that we can exchange sensitive documents etc and they want us to us a public private key set up. I’m not sure what i need to do, i have been on the Comodo site and downloaded the free SSL certificate ( i think ) I cant work out how to install the cert into my email ( outlook ). any ideas on how to set it up?? cheers guys…

It’s probably something like PGP that you want to look at to encrypt your emails rather than SSL.
