WebNov 15, 2024 · Columnar Transposition. In a columnar transposition cipher you write the message out in rows of a fixed length. Then you read out column by column, where the columns are chosen in a scrambled order. Normally the key defines the width of the rows and moreover the "scramble" part in column permutation. Take the ciphertext ... WebColumnar Transposition involves writing the plaintext out in rows, and then reading the ciphertext off in columns.
