title: OpenSSL encoding errors while converting cer to pem
body: <p>I`m trying to convert the .cer file to .pem through openssl, the command is:</p>
  
  <pre><code>openssl x509 -inform der -in certnew.cer -out ymcert.pem
  </code></pre>
  
  <p>and that's the errors I`m getting:</p>
  
  <pre><code>unable to load certificate
