If all keys use characters a-z then the following will work: N1: 64ff N2: 6dff N3: 7aff (64, 6d and 7a are hex for ascii codes of d, m, z). Here the key (in hex) 64ffff will go to N2 even though it starts with d. But every string that starts with a-d with only characters a-z afterwards will go to N1.
