<entry><p> <b>Description</b>  </p> </entry>

</row>

<row>

<entry><p> <codeph>StartEntry</codeph>  </p> </entry>

<entry><p>Specifies the certificate label. This label is in UTF-8 format and

limited to 64 characters. </p> </entry>

</row>

<row>

<entry><p> <codeph>Deletable</codeph>  </p> </entry>

<entry><p>The value of this field indicates whether the certificate can be

deleted. <codeph>True</codeph> indicates that the certificate can be deleted. <codeph>False</codeph> indicates

that the certificate must be protected from deletion. </p> </entry>

</row>

<row>

<entry><p> <codeph>Format</codeph>  </p> </entry>

<entry><p>Specifies the certificate format. This is usually set to <codeph>EX509Certificate</codeph>. </p> </entry>

</row>

<row>

<entry><p> <codeph>CertificateOwnerType</codeph>  </p> </entry>

<entry><p>Indicates the type of certificate owner. This field has the following

legal values: <codeph>ECACertificate</codeph>, <codeph>EUserCertificate</codeph> and <codeph>EPeerCertificate</codeph>. </p> </entry>

</row>

<row>

<entry><p> <codeph> SubjectKeyId</codeph>  </p> </entry>

<entry><p>Both these fields are used to build certificate chains by looking

for certificates with <codeph>SubjectKeyId</codeph> values that match the <codeph>IssuerKeyId</codeph> value

of the first certificate in the chain. While the <codeph>SubjectKeyId</codeph> enables

identification of certificates containing a public key (in this case, the

issuer key), the <codeph>IssuerKeyId</codeph> is the unique value that identifies

the issued certificate. </p> <p>These fields are optional. If omitted, their

values are considered equivalent to auto. For x509 certificates, it is recommended

that these fields be omitted or set to auto. For other certificate types,

specify an octet string value. </p> </entry>

<row>

<entry><p> <codeph> IssuerKeyId</codeph>  </p> </entry>

</row>

<row>

<entry><p> <codeph> StartApplicationList</codeph>  </p> </entry>

<entry><p>Indicates the start and end of the application list. An application

list specifies the applications associated with a certificate. Applications

can be specified by UID or by name (in which case they are looked up in <codeph>certclients.dat</codeph>). </p> </entry>

<row>

<entry><p> <codeph> EndApplicationList</codeph>  </p> </entry>

</row>

<entry><p> <codeph>Trusted</codeph>  </p> </entry>

<entry><p>The value of this field is usually set to <codeph>True</codeph>.

If set to <codeph>False</codeph>, the certificate does not act as a trust

anchor and its capabilities are not used. </p> </entry>

</row>

<row>

<entry><p> <codeph>DataFileName</codeph>  </p> </entry>

<entry><p>Specifies the name of the file from which the certificate is to

be read. </p> <p>If the certificate format is not x509, the contents are treated

as a raw block of data. If the format is x509, the file can be either of the

following: </p> <ul>

<li id="GUID-39DE0AA4-A147-51CD-B39F-044DC67BF272"><p>A Privacy Enhanced Mail

(PEM) encoded certificate in a UTF-8 file with or without a UTF-8 Byte Order

Marker (BOM) </p> </li>

<li id="GUID-176D7B07-879F-5D3F-86A5-EF18B9A450FB"><p>A binary file containing

a Distinguished Encoding Rules (DER) encoded certificate. </p> </li>

Store Field Details</title> <p>The following table provides information on

the SWI certificate store fields. Because the SWI certificate store is a superset

<row>

<entry><p> <codeph>CapabilitySet</codeph>  </p> </entry>

<entry><p>Defines a list of capabilities allowed in applications that have

the certificate as their trust anchor. Standard capability names or numeric

bit numbers can be specified. </p> </entry>

</row>

<row>

<entry><p> <codeph>Mandatory</codeph>  </p> </entry>

<entry><p>The value of this field is usually be set to <codeph>False</codeph> so

that it enables the installation of any package not signed by a certificate

that resolves to a SWI certificate. A <codeph>True</codeph> value prevents

normal installation of packages. </p> <p> <b>Note:</b> If the certificate

store is deployed in a device that does not support the feature of updating

ROM files without using SIS stubs, the certificate gets interpreted as <codeph>Mandatory</codeph>.

This prevents all normal applications from installing. </p> </entry>

</row>

<row>

<entry><p> <codeph>SystemUpgrade</codeph>  </p> </entry>

<entry><p>The value of this field must usually be set to <codeph>False</codeph> to

enable normal installation of applications. A <codeph>True</codeph> value

of this field indicates that any application signed by a certificate which

resolves to this certificate is treated as a System Upgrade, and consequently,

a lot of security checks are disabled for that application. </p> <p> <b>Note:</b> The

field is set to <codeph>True</codeph> only when the certificate store is deployed

in a device that supports the feature of updating ROM files without using

SIS stubs. </p> </entry>

</tgroup>

</table> <p> <b>Important: </b> A SWI certificate store does not have a <codeph>Deletable</codeph> field

because all the SWI certificates are protected from deletion. </p> </example>
