Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Symmetric key is
A
Sender only used same key
B
Receiver only used same key
C
Sender and receiver use same key
D
None of the above
Explanation: 

Detailed explanation-1: -Secret key cryptography (symmetrical encryption): Both the sender and receiver must use the same key to encrypt and decrypt messages being sent. This imposes a security risk as we need to deliver the key to the recipient of the message in a secure way to make him/her able to decrypt the message.

Detailed explanation-2: -Private key encryption systems use a single key that is shared between the sender and the receiver. Both must have the key; the sender encrypts the message by using the key, and the receiver decrypts the message with the same key.

Detailed explanation-3: -Symmetric encryption is a type of encryption where only one key (a secret key) is used to both encrypt and decrypt electronic data.
