title: Removing "BEGIN" and "END PGP MESSAGE" strings makes decryption break
body: <p>I am using the below command to encrypt plain text using GnuPG:</p>
  
  <pre><code>gpg2.exe --encrypt --armor --recipient &lt;&lt;recipient&gt;&gt;
  </code></pre>
  
  <p>This returns output as</p>
  
  <pre><code>-----BEGIN PGP MESSAGE-----Version: GnuPG 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DbOJ-----END PGP MESSAGE-----
  </code></pre>
  
  <p>Now when I decrypt the same string, it is decrypting back, but when I remove <code>-----BEGIN PGP MESSAGE-----Version: GnuPG v2</code> and <code>-----END PGP MESSAGE-----</code> from this string, following error message is returned:</p>
  
  <pre><code>gpg: no valid OpenPGP data found.
  gpg: decrypt_message failed: Unknown system error
  </code></pre>
  
  <p>Any Ideas?</p>
