title: DB filesystem encryption
body: <p>This is very common question everyone has but important. Is there any best tool which encrypts filesystem? Here my requirement is even if we log in to db we should see encrypted data only. It should be displayed decrypted data only in front end.</p>
  
  <p>So any one please can you suggest me a better way for implementing this. I am using PHP in LAMP server.</p>
  
  <p>Thanks in advance,
  Shilpa</p>
