title: 3DES on iOS 8+ with Objective-C
body: <p>I have to encrypt a password with 3DES and send it as parameter to login service on backend.</p>
  
  <p>I'm struggling searching an algorithm to achieve 3DES during last week but I can't be able to find it.</p>
  
  <p>I need to crypt the password with a <strong>key</strong> and an <strong>initializer vector</strong> (aka <strong>iv</strong>).</p>
  
  <p>Someone knows a free library or an algorithm appropriate?</p>
  
  <p>Thanks.</p>
