SECURING YOUR DATA


Encrypting and digitally signing e-mail messages
You can set IBMR Lotus NotesR to digitally sign and encrypt e-mail messages you send to other NotesR users or to users over the Internet.

Digital signatures are the computerized equivalent of a handwritten signature, but they are much harder to forge. In Notes, your digital signature is created with your private key and then verified with your public key.

When you send an e-mail message, the recipient's status bar element indicates if the document has been signed, encrypted, or both, as follows:


If you want to encrypt or sign mail that is being sent over the Internet, you must have an Internet certificate.

If you're working offline with an outgoing mailbox, you can encrypt the mail you send if your organization provides a mobile directory catalog. For more information, see Working online or offline.

Note: A signature can be your name with a graphic or your department information appearing in the body of an e-mail message. This type of signature is different than a digital signature. For more information on signatures, see Adding signatures to mail.
