But who'd consider that with just one-case and alphabet only...
At the least include upper, lower, numbers, and basic punctuation --
that will add a few more cycles of computation time to break <G>
But the other point, yes... The most used encryption systems have
publicly known/reviewed algorithms and rely on the secrecy of the key(s).
