S/MIME email certificate

[whsbuss]

I have installed an Instantssl free email certificate on my Mac and iPhone. Now my friend want to do the same so we can encrypt email, when required, but he has nothing but an iPhone and iPad. How can he get a certificate and install it without a Mac or PC?

Any info would be appreciated.

I used to store the certificate in dropbox, and can load from there. Maybe using the share url.
