OpalKelly DES Test Vector Failing

FrontPanel
1

I’m testing the DES example. I’m using the precompiled bitfile for XEM8350-KU060. Everything works great except the answer I get isn’t right. I know this isn’t exactly supposed to be a functional DES tool, more of just an example but I’d like to make sure I didn’t do anything wrong

Plaintext (as hex)
0000 0000 0000 0000
Key (as hex)
0000 0000 0000 0000
Using http://des.online-domain-tools.com/ I think the result should be
8c a6 4d e9 c1 b1 23 a7
But using the tool I get
A723 B1C1 E94D A68C

Seems the answer is still correct, just presented in a different endianness. Please see FrontPanel SDK Documentation: USB3.0 Byte Order in Pipes (Section 3.3.3) for more information.
