title: DocuSign how to save the Private key as a .PEM file
body: <p>From the JSON Web Token Bearer Grant guide, it was recommended that I should save the Private key as a .PEM file</p>
  
  <blockquote>
    <p>Note: If you’re working with sample code from one of the SDKs, save
    the Private key as a .PEM file. The SDK is configured to read the
    private key value from a file with this extension.</p>
  </blockquote>
  
  <p>So now that I have generated my private key:</p>
  
  <pre><code> ----BEGIN RSA PRIVATE KEY---- 
  ****
   ----END RSA PRIVATE KEY-----
  </code></pre>
  
  <p>How do I save this as a .PEM file, is it simply just pasting this private key into a notepad and instead of saving to a .txt file I should change the extension to .PEM?</p>
  
  <p>Also is there any security reason why I should save the private key as a .pem instead of .txt?</p>
