Question

In a scenario where Nancy and Matthew are using public key encryption, which keys will Nancy have the ability to see in her public keyring (--list-keys)?

Answer 1

Answer:

Private key

Explanation:

From the question, we understand that the encryption type is a public encryption.

For better analysis, I will create the following scenario.

Encryption keys are stored in an encrypted form in a PGP (i.e. Pretty Good Privacy). This PGP homes the public and the private keys.

However, for Nancy to access the public keyring, she needs the private keys.

If by chance she lost/forgot the private keys, she will not be able to decrypt any information she receives.

Hence, the solution to this question is: private key
