Certificates and PGP keys
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.

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 organisation, enrolment
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.
About the trust status of certificates and PGP keys
When you view the details for a certificate or key, you can view the trust status of the item. Depending on your
administrator, you can change the trust status of a certificate or PGP key.
A certificate can be explicitly trusted (the certificate itself is trusted), implicitly trusted (the root certificate in the certificate
chain is trusted on your BlackBerry smartphone), or not trusted (the certificate isn't explicitly trusted and the root
certificate in the certificate chain isn't trusted or doesn't exist on your smartphone).
A PGP key can be explicitly trusted (the PGP key itself is trusted), implicitly trusted (the PGP key is associated with a private
key on your smartphone), or not trusted (the PGP key isn't explicitly trusted and isn't associated with a trusted PGP key on
your smartphone, and a chain of digital signatures to a trusted key doesn't exist).
