RE: Encoding Schemes

If we're trying to fathom this out from first principals, I don't think there's enough here to get started. At the moment, all we know is that the second hex digit of every byte comes out the same in both sequences. However, since both sequences share the same low-order nibbles when encoded in hex, that doesn't necessarily help yet.
Next thing to look at is - is position important. If you rotate one of the sequences (say, try putting through BCDEFA, CDEFAB, etc), does the encoded output just rotate, or is it completely transformed. Finally, chuck through the complete upper and lowercase alphabets, so that we have all of the low-order nibble posibilities, and some more material to work with.

Subject: Encoding Schemes
I am reviewing a web app and I would like to know what
encoding scheme they are using to encode their
123456 encodes to B8DCCEA11586
ABCDEF encodes to C8ACBED165F6
Any help would be appreciated.
