Given an alphabet of length A, an input length L is valid if:
* L >= 2,
-* A^L >= 1,000,000
-* and L <= 2 * floor(logA(2^96)).
+* AL >= 1,000,000
+* and L <= 2 * floor(logA(296)).
As a concrete example, for handling credit card numbers, A is 10, L is 16, so
valid input lengths would be between 6 and 56 characters. This is because
-10^6=1,000,000 (already greater than 2), and 2 * floor(log10(2^96)) = 56.
+106=1,000,000 (already greater than 2), and 2 * floor(log10(296)) = 56.
Of course, in the case of credit card numbers valid input would always be 16
decimal digits.
