Answer:
The answer is Symmetric Key cryptography
Explanation:
Because this method of encryption allow both parties to use the same key and cipher to encode and decode the ciphertext.
Answer:The
The answer is User Cs uses the Public Key.
Explanation:
Public-key cryptography refers to a cryptographic system that uses pairs of keys: one that is a private keys,which are seen only by the use and public keys, which may be used widely by different users.
The generation of such keys depends on algorithms that are cryptographic based on mathematical problems to provide function that is one way. A strong security only needs keeping the private key private; the public key can be openly distributed among users without compromising security.
