If an asymmetric algorithm uses a public key to encrypt data, what is used to decrypt it?
- a digital certificate
- a different public key
- a private key
Explanation: When an asymmetric algorithm is used, public and private keys are used for the encryption. Either key can be used for encryption, but the complementary matched key must be used for the decryption. For example if the public key is used for encryption, then the private key must be used for the decryption.
