Configuring digital signature and encryption for emails

Configure emails that send a digital signature to verify you as an authentic sender and an email encryption to certify authentic recipients.

A digital signature verifies the email sender and assures recipients that the email came from a trusted source and wasn't altered. In the email composer for Configurable Workspace, you can select a check box to digitally sign outbound emails.

Encryption makes the email unreadable to anyone except the intended recipient. In the email composer for Configurable Workspace, you can select a check box to encrypt outbound emails.

Digital signature and encryption configuration

To use digital signature or encryption for emails in Configurable Workspace, configure S/MIME for your instance. For information on S/MIME and instructions to configure S/MIME for emails, see Setting up S/MIME for email.
