About certificates and certificate enrolment
A certificate is a digital document that binds the identity and public key of a certificate subject. Your BlackBerry smartphone supports RSA, DSA, Diffie-Hellman and ECC keys.
If your work email account uses a BlackBerry Enterprise Server that supports this feature, you can download certificates over the wireless network using a certification authority profile provided by your administrator. Depending on your organisation, enrolment for a certificate might be required and may also occur automatically.
When you enrol with a certification authority profile, a new certificate is downloaded to your smartphone and added to your certificate list. The certification authority profile shows the status of the certificate. If the certificate is scheduled to expire soon, you can re-enrol with the certification authority profile to receive an updated certificate.
