On the whole I'm inclined to do nothing here; these docs have to satisfy a number of requirements, and "every example should be copy-and-pasteable" doesn't seem like a good constraint to add. Another idea perhaps could be to remove enough digits from the example that it doesn't cause overwidth warnings in the PDF --- but I'm not sure that's feasible in a 3-column table. Or we could just drop this one example.
Another option, write:
"Same as input."
in the other two columns - so one doesn't have to look closely at some 30 characters of hex to prove to themselves the inputs and outputs are indeed identical.
Would do it elsewhere for consistency - it also does make the case stand out which I think is a plus and part of the point of the table.
