Detailed explanation-1: -Ciphertext is encrypted text transformed from plaintext using an encryption algorithm. Ciphertext can’t be read until it has been converted into plaintext (decrypted) with a key.

Detailed explanation-2: -Symmetric encryption uses the same key to perform both encryption and decryption functions. Symmetric encryption uses a shared private key while asymmetric encryption uses a public/private key pair. Another difference between asymmetric and symmetric encryption is the length of the keys.

Detailed explanation-3: -Public Key (or asymmetric encryption) In a public key system, two keys are used, one for encrypting and one for decrypting. The two keys are mathematically related to each other but knowing one key does not divulge the other key. The two keys are called the “public key” and the “private key” of the user.

Detailed explanation-4: -Asymmetric encryption uses the notion of a key pair: a different key is used for the encryption and decryption process. One of the keys is typically known as the private key and the other is known as the public key.

Detailed explanation-5: -Asymmetric encryption is also known as public key cryptography, which is a relatively new method, compared to symmetric encryption. Asymmetric encryption uses two keys to encrypt a plain text.
