§3.1.1: Simple Columnar Transposition Ciphers
1. Encipher the message we are xavier students, using a simple columnar
cipher with 5 columns. Make sure to give n, c, q, r.
2. Decipher the message TSENR OASJY DWDAA EANYD YUINI A, using a
simple columnar cipher with 6 columns. Make sure to give n, c, q, r.
3. Break the message CUKCR ABTIN RHPYE IHOAS E by hand. This is for a
simple columnar cipher. The number of columns is less than 8. Make
sure to give n, c, q, r.
4. Break the message IWTTM CAHAO AIERV NTNWI NFEAE OOWRS
TRSS on a maplet. The number of columns is less than 9. This is for a
simple columnar cipher.
