Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

Public and Private keys are needed as part of which cryptography technique?

A	Symmetric (Private Key)
B	WEP
C	Asymmetric (Shared Key)
D	HTTPS

Explanation:

Detailed explanation-1: -Asymmetric encryption uses a mathematically related pair of keys for encryption and decryption: a public key and a private key. If the public key is used for encryption, then the related private key is used for decryption.

Detailed explanation-2: -Public key cryptography is a method of encrypting or signing data with two different keys and making one of the keys, the public key, available for anyone to use. The other key is known as the private key. Data encrypted with the public key can only be decrypted with the private key.

Detailed explanation-3: -Asymmetric encryption utilizes a pair of keys like public and private key for better security where a message sender encrypts the message with the public key and the receiver decrypts it with his/her private key.

Detailed explanation-4: -Public-key (asymmetric) cryptography requires the use of a public-key and a private key.

Detailed explanation-5: -Asymmetric encryption, also known as public key encryption, uses a public key-private key pairing: data encrypted with the public key can only be decrypted with the private key. TLS (or SSL), the protocol that makes HTTPS possible, relies partially on asymmetric encryption.
