Generating an RSA Key Pair

</h1>
<a name="wp1073278"> </a><p class="pBody">
RSA key-pairs are used to sign and/or encrypt and decrypt the security payload during security protocol 
exchanges for applications such as IKE/IPsec and SSH, and they are required before you can obtain a 
certificate for your switch.

</p>
<a name="wp1077804"> </a><h2 class="pHeading2">
Detailed Steps
</h2>
<a name="wp1118851"> </a><p class="pBody">
To generate an RSA key-pair, follow these steps:

</p>
<div class="pSmartList1"><ol type="1" class="pSmartList1">
<a name="wp1118852"> </a><li class="pSmartList1">Expand <b class="cBold">Switches</b> &gt; <b class="cBold">Security</b> and then select <b class="cBold">PKI</b> in the Information pane.
</li>
<a name="wp1118853"> </a><li class="pSmartList1">Click the <b class="cBold">RSA Key-Pair </b>tab.
</li>
<a name="wp1118854"> </a><li class="pSmartList1">Click <b class="cBold">Create Row</b>. 
</li>
<a name="wp1118855"> </a><li class="pSmartList1">Select the switches for which you want to create the RSA key-pair. 
</li>
<a name="wp1118856"> </a><li class="pSmartList1">Assign a name to the RSA key-pair.
</li>
<a name="wp1118857"> </a><li class="pSmartList1">Select the Size or modulus values. Valid modulus values are 512, 768, 1024, 1536, and 2048. 
</li>
<a name="wp1118858"> </a><p class="pListNote1">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> The security policy (or requirement) at the local site (MDS switch) and at the CA (where 
enrollment is planned) are considered in deciding the appropriate key modulus.

</p>
<a name="wp1118859"> </a><p class="pListNote1">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> The maximum number of key-pairs you can configure on a switch is 16.

</p>
<a name="wp1118860"> </a><li class="pSmartList1">Check the <b class="cBold">Exportable</b> check box if you want the key to be exportable.

<strong>Caution	&nbsp;&nbsp;&nbsp;</strong>

<p>The exportability of a key-pair cannot be changed after key-pair generation.

<a name="wp1118862"> </a><p class="pListNote1">
<strong>Note	&nbsp;&nbsp;&nbsp;</strong> Only exportable key-pairs can be exported in PKCS#12 format.
