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.
