Formula for number of encryptions run on smart_decipher:
     num_of_encryptions = num_of_configurations * (26^3 + HighScores_N * 26^2)

Formula for number of encryptions run on bruteforce_decipher:
     num_of_encryptions = num_of_configurations * 26^5

For m4, use 26^4 instead of 26^3, and 26^6 instead of 26^5.
