Module cipher_crypt::columnar_transposition
source · Expand description
The Columnar cipher is a transposition cipher. In columnar transposition the message is written out in rows of a fixed length, and then transcribed to a message via the columns. The columns are scrambled based on a secret key.
Columnar transposition continued to be used as a component of more complex ciphers up until the 1950s.
