ROT13 Inspired Letter Substitution Cipher - jQuery Text Rotator

The Text Rotator jQuery plugin helps you encrypt your text by rotating the letters by a specific number of places (0-25).

Inspired by the ROT13 letter substitution cipher that provides a weak encryption for spoilers, punchlines, puzzle solutions, and offensive materials from the casual glance.

How to use it:

1. Include the Font Awesome for the icons.

<link rel="stylesheet" 
      href="https://use.fontawesome.com/releases/v5.5.0/css/all.css" 
      integrity="sha384-B4dIYHKNBt8Bc12p+WXckhzcICo0wtJAoU8YZTY5qE0Id1GSseTk6S+L3BlXeVIU"
      crossorigin="anonymous">

2. Create a textarea element for the normal text.

<div id="left-text" class="textarea-card">
  <h2>Normal Text</h2>
  <textarea name="normal-textarea" id="normal-textarea" spellcheck="false" placeholder="Enter some text here..."></textarea>
</div>

3. Create an incrementer that allows the user to adjust the number of places by clicing the up and down arrows.

<div id="incrementer">
  <button id="up-button"><i class="fa fa-arrow-up fa-3x"></i></button>
  <p id="increment-text">0</p>
  <button id="down-button"><i class="fa fa-arrow-down fa-3x"></i></button>
</div>

4. Create another textarea element to hold the encrypted text.

<div id="right-text" class="textarea-card">
  <h2>Rotated Text</h2>
  <textarea name="rotated-textarea" id="rotated-textarea" spellcheck="false" placeholder="Or enter some here..."></textarea>
</div>

5. Download and place the core JavaScript file after jQuery library. That's it.

<script src="https://code.jquery.com/jquery-3.3.1.min.js" 
        integrity="sha384-tsQFqpEReu7ZLhBV2VZlAu7zcOV+rXbYlF2cqB8txI/8aZajjp4Bqd+V6D5IgvKT" 
        crossorigin="anonymous">
</script>
<script src="index.js"></script>
