What are some classical cryptography methods?

Classical cryptography methods include 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 shifts letters by a fixed number. For example, with a shift of 3, A becomes D, B becomes E, etc.

What about the Vigenère cipher?

The Vigenère cipher uses a keyword to shift letters. Each letter of the keyword determines the shift for the corresponding plaintext letter.

Are there any weaknesses in these methods?

Yes, classical methods are vulnerable to frequency analysis and can be easily broken with modern techniques.
