How do I install a Digital Certificate onto an Apple iPhone?
An End User Digital Certificate that contains a public and private key (usually in the form of a .p12 or .pfx file) can be installed onto the iPhone or iPad. With the release of iOS 5, the iPhone and iPad now support S/MIME. This means that you can digitally sign and encrypt emails from either device. iOS 5 also has support for client authentication using a certificate. This will enable you to log onto a website that requires a certificate for access. Below are the steps in order to install a digital certificate onto an iPhone.

Important Note: Apple recommends that a *.p12 or *.pfx file is sent to your device as an attachment in an email. QuoVadis does not recommend this approach unless email access to your mail server is encrypted using SSL. Further to this note, the QuoVadis Trust/Link portal is able to deliver a *.p12 file directly to your device (providing your Account is configured with the appropriate policy).
Additional Note: All screenshots are shown using iOS7. The steps for previous versions of iOS are generally the same.
