Making a substitution during Frequency Analysis can't be reversed. #4

Open soutzis opened 4 years ago

soutzis commented 4 years ago

If a substitution is made during frequency analysis, for example A->G, all the characters 'A', will be substituted with 'g' in the cipher text. When deciding to change the substitution to something like A->K, the key will be updated, but the current cipher text (the one showing the progress) will not be updated.

This can lead the analyst to the wrong conclusion/decisions.

Dictionary with indices of each encrypted (not substituted) character. Will also help with issue #5
