title: How to combine cer and key to generate jks file
body: <p>I am new to certificates and its conversions from one form to other. I also tried exploring but finding it a bit difficult to interpret exact info. I got two files <code>gtcloud.cer</code> (certificate) and <code>gtcloud.key</code> (private key starts with <code>BEGIN_PRIVATE_KEY</code>, ends with <code>END_PRIVATE_KEY</code>). </p>
  
  <p>Now I want to merge these two to generate a single JKS file which I can use in my java application.</p>
  
  <p>Is there any GUI based software or we have to use openssl for this?</p>
