title: Generating 128 bit random key in java
body: <p>I want to generate a 128 bit random key in java. I am using the following:  </p>
  
  <pre><code>byte[] byteBucket = new byte[bytelength];
  randomizer.nextBytes(byteBucket);
  </code></pre>
  
  <p>Will my byte array length be 16 as (16*8=128) or 128?</p>
