How do I convert a pem to pfx file?
<p><a href="https://search.thawte.com/support/ssl-digital-certificates/index?page=content&amp;actp=CROSSLINK&amp;id=SO26449" rel="noreferrer">This has me confused</a>:</p>

<pre><code>Convert pfx to PEM:
openssl pkcs12 -in certificatename.pfx -out certificatename.pem
</code></pre>

<p>Do this dumps out a <strong>single</strong> plain text file.</p>

<p>Now how do I convert this plain text pem back to pfx?</p>

<p>The only commands I see to convert to pfx require the cer and private keys in separate files:</p>

<pre><code>Convert CER and Private Key to PFX:    
openssl pkcs12 -export -in certificatename.cer -inkey privateKey.key -out certificatename.pfx -certfile  cacert.cer
</code></pre>
