What are Ciphertexts?

Ciphertexts are the encrypted data that has been transformed into a code that can only be deciphered by someone with the appropriate decryption key. In other words, ciphertexts are the result of encrypting plaintext messages using an encryption algorithm and a secret key. The ciphertexts are then sent over an insecure channel, such as the internet, without fear of being intercepted or read by unauthorized parties.

Only the person or entity with the appropriate decryption key can decipher the ciphertexts and access the original plaintext message. This ensures that sensitive information remains confidential and secure, even when it is transmitted over an insecure channel.

For example, if you were to send an email to a friend using a secure email service, the plaintext message would be encrypted into ciphertext before being sent over the internet. Only your friend, who has the appropriate decryption key, would be able to decipher the ciphertext and read the original message.
