Every method I write to encode a string in Java using 3DES can&#39;t be decrypted back to the original string.  Does anyone have a simple code snippet that can just encode and then decode the string back to the original string?

I know I&#39;m making a very silly mistake somewhere in this code. Here&#39;s what I&#39;ve been working with so far:

** note, I am not returning the BASE64 text from the encrypt method, and I am not base64 un-encoding in the decrypt method because I was trying to see if I was making a mistake in the BASE64 part of the puzzle.

    public class TripleDESTest {
         
        public static void main(String[] args) {
    	
    	    String text = &quot;kyle boon&quot;;
    	
    	    byte[] codedtext = new TripleDESTest().encrypt(text);
    	    String decodedtext  = new TripleDESTest().decrypt(codedtext);
    	
        	System.out.println(codedtext);
        	System.out.println(decodedtext);
        }
    
        public byte[] encrypt(String message) {
    	    try {
			    final MessageDigest md = MessageDigest.getInstance(&quot;md5&quot;);
	            final byte[] digestOfPassword = md.digest(&quot;HG58YZ3CR9&quot;.getBytes(&quot;utf-8&quot;));
    	        final byte[] keyBytes = Arrays.copyOf(digestOfPassword, 24);
	            for (int j = 0,  k = 16; j &lt; 8;)
