The test suite needs more tests since there is more than one possible valid key.

And the problem also needs a capital letter D. You can hide the key in a P-file if you are worried about secrecy & most people won't be able to hack it. https://www.mathworks.com/help/matlab/ref/pcode.html It's bad to have more than nine valid keys, and it gets easier to guess them correctly in later problems due to the gaps.
