(Optional) One or more secret encryption keys, created and distributed by users to allow other users to encrypt and decrypt fields in a document.
Note If a user is in the process of requesting a new private key or a name change, the pending information is also stored in the ID file. If a Lotus Notes private key is changed, then the obsolete information is also stored in the ID file for backwards compatibility. For example, you would need the obsolete information to read old encrypted e-mail.
