Encrypting and Decrypting Using Java: Unable to get same output

Question

I am trying to learn and test the java 1.6 encryption/decryption API. I want to know what I am doing wrong and what I am missing in terms of knowledge.

In the code

Answer 1

Here's the description from JDK doc:

DESKeySpec
public DESKeySpec(byte[] key)
           throws InvalidKeyException
Creates a DESKeySpec object using the first 8 bytes in key as the key material for the DES key. 
The bytes that constitute the DES key are those between key[0] and key[7] inclusive. 

DESKeySpec uses only the first 8 bytes of byte[] as key. Thus the actual keys in used are identical in your example.
