Entrust/ExpressTM is the newest addition to the Entrust product family, designed for users of Microsoft Exchange. With Entrust/Express, users can encrypt and digitally sign e-mail using their Entrust keys, from within their Exchange environment. Entrust/Express also works with Microsoft Outlook, the MS Office '97 e-mail client.
Entrust/Express is a plug-in to Microsoft Exchange, providing seamless integration of Exchange with an existing Entrust public-key infrastructure (PKI). Using "encrypt" and "sign" buttons in the Exchange toolbar, users can encrypt messages, digitally sign them, or perform both operations.
