Each client and each\nserver must have a private key. A private key is created like this\n\n</p>\n<pre><code>openssl genrsa -out ryans-key.pem 1024</code></pre>\n<p>All severs and some clients need to have a certificate. Certificates are public\nkeys signed by a Certificate Authority or self-signed. The first step to\ngetting a certificate is to create a &quot;Certificate Signing Request&quot; (CSR)\nfile. This is done with:\n\n</p>\n<pre><code>openssl req -new -key ryans-key.pem -out ryans-csr.pem</code></pre>\n<p>To create a self-signed certificate with the CSR, do this:\n\n</p>\n<pre><code>openssl x509 -req -in ryans-csr.pem -signkey ryans-key.pem -out ryans-cert.pem</code></pre>\n<p>Alternatively you can send the CSR to a Certificate Authority for signing.\n\n</p>\n<p>(TODO: docs on creating a CA, for now interested users should just look at\n<code>test/fixtures/keys/Makefile</code> in the Node source code)\n\n</p>\n<p>To create .pfx or .p12, do this:\n\n</p>\n<pre><code>openssl pkcs12 -export -in agent5-cert.pem -inkey agent5-key.pem \\\n    -certfile ca-cert.pem -out agent5.pfx</code></pre>\n<ul>\n<li><code>in</code>:  certificate</li>\n<li><code>inkey</code>: private key</li>\n<li><code>certfile</code>: all CA certs concatenated in one file like\n<code>cat ca1-cert.pem ca2-cert.pem &gt; ca-cert.pem</code></li>\n</ul>\n",
