title: How to save secret key securely in android
body: <p>I just read this article <a href="http://android-developers.blogspot.in/2013/02/using-cryptography-to-store-credentials.html" rel="noreferrer">http://android-developers.blogspot.in/2013/02/using-cryptography-to-store-credentials.html</a> where I learnt to generate security key.</p>
  
  <p>I want to know how to save this generated key securely so hackers wont get this even phone is rooted.</p>
  
  <p>If we save this <code>SharedPreference</code>, <code>Storage</code> then hacker can get this.</p>
  
  <p>Thanks.</p>
