Decoding JSON and a base64-encoded value in a shell script
<p>I have a JSON and I need to extract a base64-encoded value by particular key and decode it.</p>

<p>JSON has the following structure:</p>

<pre><code>[
  {
    "LockIndex": 0,
    "Key": "Arul/key1",
    "Flags": 0,
    "Value": "MzAKCg==",
    "CreateIndex": 369,
    "ModifyIndex": 554
  }
]
</code></pre>

<p>In the above JSON, I need to extract only <code>"Value":"MzAKCg=="</code> and decode the base64-encoded <code>"MzAKCg=="</code> value. I would like to perform this using shell scripting.</p>

<p>Please assist.</p>
