Row Column Transposition Ciphering Technique

[@henriquearmani714]

India is such a blessed country. I've learned more from indians than from people of my own country. Thanks (and congratulations) to you and your nation for being so willing to share your knowledge for free with the rest of the world through KZbin.

### Detailed Decryption Steps: 1. **Setup**: - Cipher text: `TTNAAPTMTSUOAODWCOTIXKNLYPETZ` - Key: `4312567` - Number of columns: 7 (from the key length) - Number of rows: 4 (since the cipher text length is 28 and 28 / 7 = 4) 2. **Create Initial Blocks**: - Break the cipher text into blocks of 4 characters each: ``` Block 1: TTNA Block 2: APTM Block 3: TSUO Block 4: AODW Block 5: COIX Block 6: KNLY Block 7: PETZ ``` 3. **Arrange Blocks Based on Key**: - Key `4312567` tells us the order in which the columns were originally placed. - Column 1 (key 4): AODW - Column 2 (key 3): TSUO - Column 3 (key 1): TTNA - Column 4 (key 2): APTM - Column 5 (key 5): COIX - Column 6 (key 6): KNLY - Column 7 (key 7): PETZ 4. **Read the Matrix Row-wise**: - Combine the characters row by row to reconstruct the original message: - Row 1: A (from AODW), T (from TSUO), T (from TTNA), A (from APTM), C (from COIX), K (from KNLY), L (from PETZ) -> ATTACKP - Row 2: O (from AODW), S (from TSUO), T (from TTNA), P (from APTM), O (from COIX), N (from KNLY), E (from PETZ) -> OSTPONE - Row 3: D (from AODW), U (from TSUO), N (from TTNA), T (from APTM), I (from COIX), L (from KNLY), T (from PETZ) -> DUNTILT - Row 4: W (from AODW), O (from TSUO), A (from TTNA), M (from APTM), X (from COIX), Y (from KNLY), Z (from PETZ) -> WOAMXYZ 5. **Combine the Rows**: - Concatenate all rows to get the original message: ``` ATTACKPOSTPONEDUNTILTWOAMXYZ ``` ### Final Decrypted Message: The decrypted message is `ATTACKPOSTPONEDUNTILTWOAMXYZ`.

how we will decide the key numbers?

[@saisk7698]

randomly chosen

[@akarshmalhotra1154]

Randomly a key is choosen , lets say if we choose 'AKARSH' then the number corresponding would be '0 10 0 17 18 7'

[@neelamyadav7609]

The key can be also decided by the sender . And this key info will be shared only between sender and receiver.

[@silent_charted72]

Then whole key is used 🤔​@@akarshmalhotra1154
