DES-Encrypt a byte array, java

Question

Now, I want to encrypt a byte array with this. How can I do that?

I have changed the name of algo from DESede to DES and am obviously using an 8-byte key (not 24).

Why do you want to use DES? It's not secure anymore nowadays. — Artjom B., Sep 23 '15 at 14:08
Its implementation based. I'm implementing something that uses DES number of times to encrypt data. — vish4071, Sep 23 '15 at 14:11

Cipher#doFinal takes and returns byte[]. The only thing that you need to do is removing the additional encoding steps like

message.getBytes("utf-8") // before encryption

and

new String(plainText, "UTF-8") // after decryption

Obviously, you need to change the method signature from String to byte[] for both encryption and decryption.
