title: Is is possible to encrypt in a different order than decrypting?
body: <p>Is it possible to encrypt in one order and decrypt in another?  For example I've got the following:</p>
  
  <ul>
  <li>plain_text.txt</li>
  <li>Public/Private Key pair 1</li>
  <li>Public/Private Key pair 2</li>
  </ul>
  
  <h2>Example</h2>
  
  <p>Encryption:</p>
  
  <pre><code>public1(public2(plain_text.txt))
  </code></pre>
  
  <p>Decryption:</p>
  
  <pre><code>private1(private2(encrypted))
  </code></pre>
  
  <p>Is there any encryption algorithm that allows this? Is it even possible?</p>
