<title>Creating an API Signing Key Pair</title>
<body>
<p>To use the cloud integration features of <ph conkeyref="vbox-conkeyref-phrases/product-name"/>, you must generate
an API signing key pair that is used for API requests to <ph conkeyref="vbox-conkeyref-phrases/oci"/>. </p>
<p>Your API requests are signed with your private key, and <ph conkeyref="vbox-conkeyref-phrases/oci"/> uses the
public key to verify the authenticity of the request. You must upload the public key to the <ph
conkeyref="vbox-conkeyref-phrases/oci"/> Console. </p>
<note>
<p>
This key pair is not the same SSH key that you use to access
compute instances on <ph conkeyref="vbox-conkeyref-phrases/oci"/>.
</p>
</note>
<ol>
<li>
<p>(Optional) Create a <filepath>.oci</filepath> directory to store the key pair. </p>
<pre xml:space="preserve">$ mkdir ~/.oci</pre>
<p>The key pair is usually installed in the <filepath>.oci</filepath> folder in your home directory. For
example, <filepath>~/.oci</filepath> on a Linux system. </p>
</li>
<li>
<p>Generate the private key. </p>
<p>Use the <codeph>openssl</codeph> command. </p>
<ul>
<li>
<p> To generate a private key with a passphrase (prompt for passphrase): </p>
<pre xml:space="preserve">$ openssl genrsa -out ~/.oci/oci_api_key.pem -aes256 2048 </pre>
</li>
<li>
<p> To generate a private key with a passphrase entered on the command line as an argument:</p>
<pre xml:space="preserve">$ openssl genrsa -aes256 -passout pass:user_passphrase -out ~/.oci/oci_api_key.pem 2048</pre>
</li>
<li>
<p>
To generate a private key without a passphrase:
</p>
<pre xml:space="preserve">$ openssl genrsa -out ~/.oci/oci_api_key.pem 2048</pre>
</li>
</ul>
</li>
<li>
<p>Change permissions for the private key. </p>
<pre xml:space="preserve">$ chmod 600 ~/.oci/oci_api_key.pem</pre>
<p>Generate the public key. </p>
<pre xml:space="preserve">$ openssl rsa -pubout -in ~/.oci/oci_api_key.pem -out ~/.oci/oci_api_key_public.pem</pre>
<p>Enter the passphrase when prompted, if you set one.</p>
</li>
</ol>
