I am studying classical ciphers and have the following doubts:
- Is the row and columnar transposition cipher the same?
It is similar since the process of encryption and decryption is the same for both(my opinion).
- How did the author get the ciphertext using row transposition cipher? (link: http://williamstallings.com/Extras/Security-Notes/lectures/classical.html)
Key(R): sorcery => 6 3 4 1 2 5 7
