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

Asymmetric cryptography uses 1 key for both encryption and decryption?

A	True
B	False
C	Either A or B
D	None of the above

Explanation:

Detailed explanation-1: -Asymmetric encryption algorithms use two different keys for encryption and decryption. The key used for encryption is the public key, and the key used for decryption is the private key. Both the keys must belong to the receiver.

Detailed explanation-2: -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. If the private key is used for encryption, then the related public key is used for decryption.

Detailed explanation-3: -Asymmetric cryptography uses two keys: if you encrypt with one key, you may decrypt with the other. Hashing is a one-way cryptographic transformation using an algorithm (and no key).

Detailed explanation-4: -The correct response is true. Asymmetric keys use two separate keys, one key to encrypt and one key to decrypt information. These are known as public and private key pairs.

Detailed explanation-5: -Answer and Explanation: The given statement is true. Symmetric encryption system uses only one key to encrypt and decrypt the data.
