A certificate + chain is a hierarchical series of certificates signed by successive + certificate authorities (CAs). A CA certificate identifies a + <a href="glossary.xhtml#certificate_authority">certificate authority</a> + and is used to sign certificates issued by that authority.

For fields whose contents the Certificate Manager cannot + interpret, it displays the actual values contained in the certificate.</p> + +<h2 id="choose_security_device">Choose Security Device</h2> + +<p>A security device (sometimes called a token) is a hardware or software + device that provides cryptographic services such as encryption and decryption + and stores certificates and keys. The Choose Security Device window appears + when Certificate Manager needs help deciding which security device to use + when importing a certificate or performing a cryptographic operation, such as + generating keys for a new certificate. This window allows you to select one + of two or more security devices that Certificate Manager has detected on your + machine.</p> + +<p>A smart card is one example of a security device. For example, if a smart + card reader connected to your computer has a smart card inserted in it, the + name of the smart card will show up in the drop-down menu. In this case, you + must choose the name of the smart card from the menu to let Certificate + Manager know that you want to use it.</p> + +<p>The Certificate Manager also supplies its own default, built-in security + device, which can always be used no matter what additional devices are or + aren't available.</p> + +<h2 id="encryption_key_copy">Encryption Key Copy</h2> + +<p><a href="glossary.xhtml#certificate_authority">Certificate authorities (CAs)</a> + that issue separate signing and encryption email certificates typically make + backup copies of your private + <a href="glossary.xhtml#encryption_key">encryption key</a> during the + certificate enrollment process.</p> + +<p>The Encryption Key Copy dialog box allows you to approve the creation of + such a backup or cancel the certificate request. A CA that has archived a + backup copy of your encryption key has the potential capability of + decrypting any messages you receive that were encrypted with your + corresponding public key.</p> + +<p>You can take these actions from the Encryption Key Copy dialog box:</p> + +<ul> + <li><strong>View Certificate</strong>: To view the certificate identifying + the CA that is requesting the backup copy, click View Certificate.</li> + <li><strong>OK</strong>: If you trust the CA identified by the CA certificate + to decrypt encrypted messages that you receive, click OK. + + <p>If you are not sure whether to trust the CA that is requesting the + backup copy, talk to your system administrator.</p> + </li> + <li><strong>Cancel</strong>: If you don't trust the CA that is + requesting the backup copy, don't request a certificate from it. Click + Cancel to stop both the backup procedure and the request for a + certificate.</li> +</ul> + +<p>After your CA makes a backup copy of the encryption key, you will be able to + use that key to access your encrypted mail even if you lose your password or + lose your own copy of the key. If no backup copy of your encryption key + exists and you lose your password or the key, you will have no way of reading + email messages that were encrypted with that key.</p> + +<h2 id="certificate_backup">Certificate Backup</h2> + +<p>When you receive a certificate, make a backup copy of the certificate and + its private key, then store the copy in a safe place. For example, you can + put the copy on a floppy disk and store it with other valuable items under + lock and key. That way, even if you have hard disk or file corruption + problems, you can easily restore the certificate.</p> + +<p>It can be inconvenient, at best, and in some situations catastrophic to lose + your certificate and its associated private key, depending on what you use it + for. For example:</p> + +<ul> + <li>If you lose a certificate that identifies you to important websites, you + will not be able to access those websites until you obtain a new + certificate. </li> + <li>If you lose a certificate used to encrypt email messages, you will not + be able to read any of your encrypted email—including both encrypted + messages that you have sent and encrypted messages that you have received. + In this case, if you cannot obtain a backup of the private encryption key + associated with the certificate, you will never be able to read any of the + messages encrypted with that key.</li> +</ul> + +<p>Like any other valuable data, certificates should be backed up to avoid + future trouble and expense. Do it now so you don't forget.</p> + +<h2 id="user_identification_request">User Identification Request</h2> + +<p>Some websites require that you identify yourself with a certificate rather + than a name and password, because certificates provide a more reliable form + of identification. This method of identifying yourself over the Internet is + sometimes called + <a href="glossary.xhtml#client_authentication">client authentication</a>.</p> + +<p>However, Certificate Manager may have more than one certificate on file that + can be used for the purposes of identifying yourself to a website. In this + case, Certificate Manager presents the User Identification Request dialog + box, which displays two kinds of information:</p> + +<p><strong>This site has requested that you identify yourself with a + certificate</strong>: This section of the dialog box lists the following + information:</p> + +<ul> + <li><strong>Host name</strong>: The name of the server requesting + identification, used as part of its URL.

You can + select any of the following options:</p> + +<ul> + <li><strong>Trust this CA to identify websites</strong>: Website certificates + for some sites, such as those that handle financial transactions, can be + extremely important, and inappropriate or false identification can have + negative consequences.</li> + <li><strong>Trust this CA to identify email users</strong>: If you intend to + send email users confidential information in encrypted form, or if accurate + identification of email users is important to you for any other reason, you + should consider carefully the CA's procedures for identifying + prospective certificate owners and whether they are appropriate for your + purposes before selecting this option.</li> + <li><strong>Trust this CA to identify software developers</strong>: Selecting + this option means that you trust the CA to issue certificates that identify + the origin of Java applets and JavaScript scripts requesting special access + to your computer, such as the ability to change files. Since such access + privileges can be misused, for example to destroy data stored on your hard + disk, be very careful about selecting this option unless you are certain + that you trust the CA for this purpose.</li> +</ul> + +<p>Before you decide to trust a new CA, make sure that you know who is + operating it. Make sure the CA's policies and procedures are + appropriate for the kinds of certificates it issues. For example, if the CA + issues certificates identifying websites you use for financial transactions, + make sure you are comfortable with the level of assurance the CA + provides.</p> + +<ul> + <li><strong>View</strong>: Click this button to view the CA certificate you + are about to download.
