title: Join two Base64 strings and then decode them
body: <p>I'm trying to figure out how to join two strings that are encoded Base64 and then decode and get the combined result.</p>
  
  <p><b>Example:</b></p>
  
  <p>string1 Hello  ---  string1 Base64  SGVsbG8=</p>
  
  <p>string2  World  ---  string2 Base64  V29ybGQ=</p>
  
  <p>If I join the base64 I get something that wont decode SGVsbG8=V29ybGQ=</p>
  
  <p>I want the result to say: Hello World</p>
  
  <p>I don't want only this example to work but rather something that will work with any string. 
  This is a very simplified problem which is a step on an application I'm trying to write I'm stuck on.</p>
