Securing your email

You can digitally sign or encrypt messages if you use a work email account that supports S/MIME-protected messages or 

IBM Notes email encryption on your BlackBerry device. Digitally signing or encrypting messages adds another level of 

security to email messages that you send from your device.
Digital signatures are designed to help recipients verify the authenticity and integrity of messages that you send. With S/

MIME-protected messages, when you digitally sign a message using your private key, recipients use your public key to 

verify that the message is from you and that the message hasn't been changed.
Encryption is designed to keep messages confidential. With S/MIME-protected messages, when you encrypt a message, 

your device uses the recipient’s public key to encrypt the message. Recipients use their private key to decrypt the 

message.
If your device is associated with a CRL or an OCSP server, when you add recipients to an encrypted message, your device 

tries to retrieve a certificate status for each recipient. You are unable to send the message until certificate statuses are 

received for all recipients. When the certificate statuses are received, the recipients' names change color, and you can 

send your message.

Color

Certificate Status

Blue

The certificate is being retrieved, validated, or the 

certificate is valid.

Red

No certificate is found, or the certificate is not valid.

Purple

The certificate can't be trusted, is unverified, or is 

unknown.
