The RSA algorithm uses a ____________ cryptography method.
-
public key
-
private key
-
symmetric
-
none of these
A
Correct answer
Explanation
RSA (Rivest-Shamir-Adleman) is a public-key (asymmetric) cryptography algorithm. It uses a pair of keys: a public key for encryption and a private key for decryption. This is different from symmetric cryptography (like AES) which uses the same key for both operations.
