title: Make a iv from a hex string in java?
body: <p>I have a 32 length hex string in Java and need to make an IV to encrypt. I know dart has a function IV.fromBase16, and I need something like that in Java. </p>
  
  <p>I tried reverse engineering through flutter, but nothing made sense. I'm new to this part of development. </p>
  
  <p>I already tried codec jar but it was worthless. I googled for questions to transform 32 to 16, but all that I have found was how to transform a string in hex values. </p>
  
  <p>Also, I need to use AES and CBC, but I'm not aware if this is possible in Java due to the string length.</p>
