12.3.2 Encrypting a mail file on a workstation
552 Lotus Security Handbook
With Domino R5.09 or later it is possible to encrypt the iNotes mail file locally
when the offline capabilties of iNotes are utilized. An encrypted mail file cannot
be opened by others without authentication. Users can select simple, medium, or
strong encryption for the offline mail file.
When selecting an encryption strength, consider the following:
► Simple encryption provides protection against casual snooping. It provides
the fastest database access but is considered to be weak encryption.
► Medium encryption provides a balance between security and fast database
access. This is likely the right encryption strength for most users.
► Strong encryption should be used when security requirements are paramount
and the users feel that the resulting database access performance is
acceptable.
To encrypt the mail file, select the Preferences menu from the iNotes interface.
On the Other tab select “Encrypt mail file locally.” The mail file is then encrypted
locally next time the local mail file is synchronized.
Users should understand that if they want to safeguard their offline mail by
encrypting it, they must enable encryption before they create an offline copy of
their mail. If they have already installed an offline copy of their mail, follow these
steps:
1. Delete the offline copy using the Offline Sync Manager.
2. With iNotes Web Access, click Preferences - Other, then select “Encrypt local
mail file.”
3. Click “Go Offline,” then select “Install Subscription” to reinstall the
subscription (offline mail copy).
Note: If the user does not see the “Encrypt mail file locally” option in the offline
section, this feature may have been turned off by the administrator.
