title: Creating/Decrypt passwords with Salt/IV
body: <p>I've been ask to do a task in a project that involves encryption on a windows 8.</p>
  
  <p>The scenario is something like this:</p>
  
  <p>I get a <code>byte[]</code> from a server, the first 16 bytes are the <code>IV</code>, the next 128 are the <code>Salt</code> and the remaining ones are the File itself.</p>
  
  <p>The user then provides a password and with that and the salt i should create a PKCS5 Key with 40 iterations and the key should have 32bytes length.</p>
  
  <p>Right now i've splitted the <code>byte[]</code> in th 3 i require, but i dont know how the rest is done in windows C#.</p>
