About PGP keys

A PGP® key might contain several cryptographic keys, including a parent key to verify signatures and one or more subkeys to encrypt messages. PGP keys are generated in pairs, with a public key and a private key.
A PGP public key binds the identity and the public cryptographic information of the PGP public key user. A PGP public key is required to verify and encrypt messages. PGP public keys are shared and are accessible by both message senders and recipients.
A PGP private key is required to sign and decrypt messages. Private key information is never publicly available.
You can generate a PGP key using the PGP Universal™ Server or PGP Desktop client. If you generate the PGP key using the PGP Universal Server, the PGP Universal Server signs the key to verify that the key is trusted.
A PGP key might also contain an X.509 certificate, which is used to verify and encrypt Secure Multipurpose Internet Mail Extensions (S/MIME) messages. If you use the PGP Universal Server and you have installed the S/MIME Support Package for BlackBerry devices, you can use these certificates to send and receive S/MIME messages through the PGP Universal Server. Certificates that you obtain from PGP keys are stored in the key store and appear in the Certificates screen.

About the key store

The key store on your BlackBerry® device stores the following items:
• Personal PGP® keys (public and private key pairs)
• PGP public keys downloaded from a Lightweight Directory Access Protocol (LDAP) server
• PGP public keys imported from a message
• Secure Multipurpose Internet Mail Extensions (S/MIME) certificates downloaded from an LDAP server
• S/MIME certificates imported from a message
The key store is protected by a key store password. Your device might prompt you to set the key store password the first time that you open the key store. You might need to type this password when adding items to or deleting items from the key store, or when an application tries to access your private key to sign or decrypt a message.

About digital signatures and encryption

You can digitally sign a message to help the recipient verify the authenticity and integrity of the message. When you digitally sign a message using your private key, the recipient uses your public key to verify that you sent the message and not someone who was pretending to be you, and that no one changed the message before it arrived.
You can encrypt a message to keep the message confidential. When you encrypt a message, your BlackBerry® device uses the recipient’s public key to encrypt the message. Only the recipient’s private key can decrypt the message and the recipient knows that no one else read the message.
Related topics
About encryption icons (See page 19.) About signature icons (See page 20.)

About encryption icons

When you open an encrypted message, a lock icon represents the encryption status. Your system administrator sets an IT Policy that determines whether the encryption algorithm that the message uses is considered to be strong or weak.
• Lock: The message is strongly encrypted.
• Lock with a question mark: The message is
weakly encrypted.

About signature icons

When you open a digitally signed message, a ribbon icon represents the verification status of the digital signature.
• Ribbon with a check mark: Your BlackBerry® device verified the digital signature.
• Ribbon with an X: Your device could not verify the digital signature.
• Ribbon with a question mark: Your device requires more data to verify the digital signature.
The icon after the ribbon icon represents the status of the sender’s PGP® key.
• Certificate with a check mark: The sender’s PGP key is trusted.
• X: The sender’s PGP key cannot be found on your device, is revoked, is not trusted, or cannot be verified, or the sender’s email address does not match the email address in the key.
• Question mark: Your device requires more data to verify the trust status, or it considers the key status to be stale.
• Clock: The sender’s PGP key has expired.

Notes:
The Fetch Sender’s PGP key menu item appears only if the sender’s PGP key is not included in your BlackBerry® device key store or the sender’s message.
If you use the PGP Universal™ Server, you might not be able to download the sender’s PGP key, or your device might download the sender’s key from the PGP Universal Server automatically.

About message classifications

If your BlackBerry® device is integrated with an account that uses BlackBerry Enterprise Server Version 4.1.2 or later and your system administrator turns on message classifications, the BlackBerry Enterprise Server applies a minimum set of security actions to each message that you compose, forward, or reply to, based on the classification that you assign to the message. Your system administrator configures the set of message classifications that you can use.
