title: Encryption of Strings works, encryption of byte[] array type does not work
body: <p>I am using the following <a href="http://www.code2learn.com/2011/06/encryption-and-decryption-of-data-using.html" rel="nofollow noreferrer">LINK</a>  for encryption and tried it with Strings and it worked. However, since I am dealing with images,  I needed the encryption/decryption process to happen with byte arrays. So I modified the code in that link to the following:</p>
  
  <pre><code>public class AESencrp {
  
      private static final String ALGO = "AES";
      private static final byte[] keyValue = 
      new byte[] { 'T', 'h', 'e', 'B', 'e', 's', 't',
  'S', 'e', 'c', 'r','e', 't', 'K', 'e', 'y' };
  
      public static byte[] encrypt(byte[] Data) throws Exception {
          Key key = generateKey();
          Cipher c = Cipher.getInstance(ALGO);
          c.init(Cipher.ENCRYPT_MODE, key);
          byte[] encVal = c.doFinal(Data);
          //String encryptedValue = new BASE64Encoder().encode(encVal);
          return encVal;
      }
  
      public static byte[] decrypt(byte[] encryptedData) throws Exception {
          Key key = generateKey();
          Cipher c = Cipher.getInstance(ALGO);
          c.init(Cipher.DECRYPT_MODE, key);
  
          byte[] decValue = c.doFinal(encryptedData);
          return decValue;
      }
  
      private static Key generateKey() throws Exception {
          Key key = new SecretKeySpec(keyValue, ALGO);
          return key;
      }
  </code></pre>
  
  <p>and the checker class is:</p>
  
  <pre><code>public class Checker {
  
      public static void main(String[] args) throws Exception {
  
          byte[] array = new byte[]{127,-128,0};
          byte[] arrayEnc = AESencrp.encrypt(array);
          byte[] arrayDec = AESencrp.decrypt(arrayEnc);
  
          System.out.println("Plain Text : " + array);
          System.out.println("Encrypted Text : " + arrayEnc);
          System.out.println("Decrypted Text : " + arrayDec);
      }
  }
  </code></pre>
  
  <p>However my output is:</p>
  
  <pre><code>Plain Text : [B@1b10d42
  Encrypted Text : [B@dd87b2
  Decrypted Text : [B@1f7d134
  </code></pre>
  
  <p>So the decrypted text is not the same as plain text. What should I do to fix this knowing that I tried the example in the original link and it worked with Strings?</p>
