What are some classical cryptography methods?

Classical cryptography methods include techniques like the Caesar cipher, Vigenère cipher, and transposition ciphers. Would you like to know how they work?

Yes, can you explain the Caesar cipher?

The Caesar cipher is a substitution cipher where each letter in the plaintext is shifted a certain number of places down or up the alphabet. For example, with a shift of 3, A becomes D, B becomes E, and so on.

What about the Vigenère cipher?

The Vigenère cipher uses a keyword to determine the shift for each letter in the plaintext. It’s more secure than the Caesar cipher because it employs multiple Caesar ciphers based on the letters of the keyword.

Are there any modern applications of these methods?

While classical methods are not used for secure communication today, they are still studied for educational purposes and can be found in puzzles and games.
