title: Base64 encoding, DONT_BREAK_LINES option
body: <p>I am using Base64.encodeBytes to encode by signed data, but it adds new line character to the generated string (for every 76 characters).
  I found out that there is an option to pass <code>DONT_BREAK_LINES</code> to avoid new line chars.</p>
  
  <p>But the description of this fields says  <code>/** Don't break lines when encoding (violates strict Base64 specification) */</code></p>
  
  <p>Can someone please explain, why using this option violates Base64 spec ?</p>
