cryptography (for example, when a user receives an e-mail protected with<br />

strong encryption where the user’s Notes multi-purpose certificate was used<br />

by another user to send that user encrypted mail). Most users use Notes<br />

multi-purpose certificates only.<br />

► Notes international certificates are used for encryption only. They allow<br />

anyone who can't use strong encryption to send encrypted e-mails. They are<br />

generally not for the user’s personal use. Every user has an international<br />

certificate in their User ID, even if it is not used.<br />

► Flat certificates were used in Notes 4.6 and earlier and are used to access<br />

pre-Release 5 servers that still use flat certificates to identify themselves. Flat<br />

certificates do not have hierarchical names. Since Release 5 of Notes and<br />

Domino, it is not possible to create new flat certificates, which means that in<br />

order for a user to have a flat certificate and be able to use it as the Notes<br />

login certificate in that user’s ID, that user had to have already had it when<br />

they upgraded to Notes 5 or later.<br />

Viewing Notes certificates<br />

You can to view all of the certificates present in a Notes user ID by choosing<br />

File → Security → User Security (for Apple Macintosh users, the command is<br />

Notes → Security → User Security). Then enter the password that protects<br />

the Notes ID and click Your Identity → Your Certificates. There are two options<br />

for which Notes certificates to view. Choose “Your Notes Certificates,” as shown<br />

in Figure 6-4, to view the certificates that can be used to log in to Notes, to<br />

access Notes databases, and to exchange secure mail with other Notes users.
