Certificates and PGP keys
About certificates and certificate enrollment
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
organization, enrollment for a certificate might be required and might also occur automatically.
When you enroll 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-enroll with the certification authority profile to receive an updated certificate.
About PGP keys
If your work email account uses a BlackBerry Enterprise Server that supports this feature, you can download PGP keys
over the wireless network from a certificate server provided by your administrator. Depending on your organization,
enrollment with the
PGP Universal Server might be required and might also occur automatically.
PGP keys allow you to send and receive PGP messages using your BlackBerry smartphone. Your smartphone supports
RSA, DSA, and Diffie-Hellman keys.
