Thanks Jon.

I forwarded your ideas to the client and he is going to run some more tests and send me back the results.
He's pretty excited!

Having done some testing...

one way of interpreting your example is that it's starting
with an offset of 0x04 for the second character, then
reducing that offset by an additional 0x06 for each
subsequent character.

This breaks very quickly, so I doubt it's right - however, if the offset is indeed generated by an algorithm it may possible to deduce it from some more
examples.

Tim's suggestion of checking whether passwords are encrypted identically for different usernames is a very good one and if that is the case with this system
then it's going to be a bit of a pain to get this sorted out.

Cheers
Jon
