Puzzle Goal
Recover the original quote from the multi-encrypted cipher text.
In each line of the quote, a letter in the original (plain) quote
has been replaced with a letter from the cipher. In the example
below, in the 1st line, every 'A' in the original (plain) quote would appear
as a 'C' in cipher, while in the 2nd line every 'A' would appear as a 'W' and in
the 3rd line every 'A' would appear as an 'R'.
The encipherments of each line are related, so that solution is
aided by working back and forth between the cryptogram and the
recorded Plain/Cipher components below the cryptogram. Each line of
the Plain is the same sequence at an offset, as in the example below:
Plain 1: TGBOMQLEYPSWVXAKHDRJZICNUF
Plain 2: OMQLEYPSWVXAKHDRJZICNUFTGB
Plain 3: MQLEYPSWVXAKHDRJZICNUFTGBO
Cipher : NTSQGXOMFPRWBECHJVKZUDALIY
In solving, therefore, if a T and B are recovered for the 1st line of
the cryptogram and are two characters apart (as above), when a T is entered
in the 2nd line the B can be entered two characters apart to assist
solution:
Plain 1: T.B.......................
Plain 2: .......................T..
Plain 3: ..........................
Cipher : NTSQGXOMFPRWBECHJVKZUDALIY
can be updated to
Plain 1: T.B.......................
Plain 2: .......................T.B
Plain 3: ..........................
Cipher : NTSQGXOMFPRWBECHJVKZUDALIY
and the on-line solving apllet will automatically decrypt any cipher Y in the 2nd
line of the cryptogram as B.
