<p>The Secure Software Install Device Tools component comprises of the following

tools: </p>

<ul>

<li id="GUID-F88142E0-F3F6-50BC-B17D-EBFC9F0D144A"><p> <b> Secure Software

Install Certificate Store tool</b> (<i>swicertstoretool</i>) - The swicertstoretool

is used to create the <filepath>swicertstore.dat</filepath> file that contains

certificates and their capabilities. SWI uses <filepath>Swicertstore.dat</filepath> file

to verify the SIS files being installed and do a capability check. </p> </li>

<li id="GUID-FBE52F5E-1D5A-5D66-9441-714375B42A8C"><p> <b> Console based SWI

<dt>Distinguished Encoding Rules (PEM )</dt>

<dd><p>PEM is a method for encoding a data object, such as an X.509 certificate,

to be digitally signed or to have its signature verified. PEM is just base64-encoded

DER, plus a header and footer. </p> </dd>

<section><title>Typical uses</title><p><b> Creating swicertstore.dat file</b></p> <p>The

swicertstore tool creates the <filepath>swicertstore.dat</filepath> file.

This file contains certificates and their capabilities which SWI uses to validate

the SIS files being installed on the device. For more information on creating <filepath>swicertstore.dat</filepath> file,

see <xref href="GUID-CF0D81FC-B28C-5AB1-BF99-A1247E31ACBF.dita">Creating swicertstore.dat

file</xref>. </p><p><b>Using console-based SWI</b> </p> <p>Native software

can be installed on the device using a console-based tool. This tool can be

used from EShell to install, uninstall or upgrade native software on the device.

For more information on using this tool, see <xref href="GUID-DA8908E9-28C7-5200-A5B2-EC1ED60ABE90.dita">Using

Console-based SWI</xref>. </p> </section>
