<h1 class="topictitle1">Manage certificates from a public Internet CA</h1>
<div><p>Review this information to learn how to manage certificates
from a public Internet CA by creating a certificate store. </p>
<p>After careful review of your security needs and policies, you have decided
that you want to use certificates from a public Internet Certificate Authority
(CA), such as VeriSign. For example, you operate a public Web site and want
to use the Secure Sockets Layer (SSL) for secure communication sessions to
ensure the privacy of certain information transactions. Because the Web site
is available to the general public, you want to use certificates that most
Web browsers can recognize readily. </p>
<p>Or, you develop applications for external customers and want to use a public
certificate to digitally sign the application packages. By signing the application
package, your customers can be sure that the package came from your company
and that unauthorized parties have not altered the code while it was in transit.
You want to use a public certificate so that your customers can easily and
inexpensively verify the digital signature on the package. You can also use
this certificate to verify the signature before sending the package to your
customers.</p>
<p>You can use the guided tasks in Digital Certificate Manager (DCM) to centrally
manage these public certificates and the applications that use them for establishing
SSL connections, signing objects, or verifying the authenticity of digital
signatures on objects. </p>
<p><span class="uicontrol">Manage public certificates</span></p>
<p>When you use DCM to manage certificates from a public Internet CA, you
must first create a certificate store. A certificate store is a special key
database file that DCM uses to store digital certificates and their associated
private keys. DCM allows you to create and manage several types of certificate
stores based on the types of certificates that they contain. </p>
<div class="p">The type of certificate store that you create, and the subsequent tasks
that you must perform for managing your certificates and the applications
that use them, depends on how you plan to use your certificates. <div class="note"><span class="notetitle">Note:</span> DCM
also allows you to manage certificates that you obtain from a Public Key Infrastructure
for X.509 (PKIX) Certificate Authority.</div>
To learn how to use DCM to create
the appropriate certificate store and manage public Internet certificates
for your applications, review these topics:</div>
