<li><p>The private key can be specified as an argument while signing an installation
file using the SignSIS tool. For details, see <xref href="GUID-B20EE8A3-D7B2-5872-AF43-001A88C1A46E.dita">SignSIS</xref>.</p></li>
<li><p>Symbian developer must send the certificate request to a trusted third
party, that is, a Certificate Authority (CA) for signing. </p><p>The CA verifies
the identity of the originator of the certificate request. After verification,
the CA signs the public key (contained in the certificate request) using the
CA's private key and creates a signed certificate. This signed certificate
is then sent back to the applicant.</p><p>The CA can return a single certificate
or a file containing a chain of certificates. This includes intermediate certificates
in addition to the CA's root certificate and the Symbian developer certificate.
 </p><note type="important">Certificates returned by CA must be in the base64
encoded ASCII format.</note></li>
<li><p>The digital certificate returned by the CA must be bundled with the
installation file to allow the digital signature to be verified. The self-signed
certificate can then be discarded.  </p></li>
