title: OPENSSL vs IPSEC
body: <p>just a very general question, but can somebody tell me when I use openSSL and
  when IPSEC to secure data transfer over the internet? It seems both of them
  are doing the same, only at different levels of the network protocol. So 
  I am not absolutely sure why we need both of them.</p>
  
  <p>Cheers for your help</p>
