Set up S/MIME-protected messaging

You need to store a private key and certificate on your BlackBerry device to send signed or encrypted email messages using S/MIME-protected messaging. You can store a key and certificate by importing the files from a work email message.

1.Open a work email message with a certificate attachment.
2.Touch and hold .
3.Tap .
4.If necessary, enter the password.
5.Tap .
6.Tap > > Secure Email.
7.If necessary, tap the S/MIME tab.
8.Set the S/MIME switch to On.
9.Below Signing Certificate, in the drop-down list, tap the certificate that you imported.
10.Below Encryption Certificate, in the drop-down list, tap the certificate that you imported.

Sign or encrypt a message

You must use a work email account that supports S/MIME-protected messages or IBM Notes mail encryption to send a signed or encrypted email message.

1. When you compose a message, slide your finger down on the screen.
2. In the drop-down list, tap a signing or an encryption option.

Tip: You can change the default email security used for messages you send. For example, if you use S/MIME to protect your messages, you can send clear-signed messages that can be opened by any email application, or opaque-signed messages that can be opened only by email applications that support encryption. In the BlackBerry Hub, tap > > Secure Email. If necessary, tap S/MIME or NNE. Change the email security settings.
