Fixed up so you can see what problem the poker.txt-file belongs to.
Figured out that the password was "god" by doing a letter frequency
analysis. The most common third number in the three-character cycle
turned out to be 1, so I just looked for a number that also had a
high frequency and appeared very commonly two spots before (because the
is extremely common and t is the second most common letter in english),
i found the sequence 19, 7, 1 to be very common and used xor with the
coded letter of each and the result was "god". Then it was just a
question of decoding the text and summing up.
