12 years ago - Text read-in/read-out options available in the main User interface (not just the text wizard)
- Switching the pre-analysis text transformation on/off is now possible in the main interface (not just the text wizard)
- Warning indicates when a ciphertext may note be solvable with the transposition analysis: This happens when a text was encrypted with column-wise read-out of the transposition table after transposing the columns, and when the table was fully filled with characters (e. g. 13 character plaintext, column count 5 => in the last row, 2 spots are free, and no filling up with placeholders). The analysis of such ciphers is a bit more difficult then the other single-round columnar transposition ciphers, because the right solution cannot be seen easily with the naked eye. I won't go into too much detail here, but the transposition of the empty spots in the last row and the column-wise read-out produce columns of different lengths which are appended and without the right key, the lengths of these read-out columns cannot be reproduced. The difference of the column lengths is 1 at maximum but this suffices to make the text hard to decipher; so I decided it is may not be in the scope of this plugin to decipher such texts
