I thought private keys were only for decryption, not encryption!

I recall that in public key cryptography, the public key is used to encrypt messages, and the private key is what allows you to decrypt them. So, I think D is definitely the best choice here.

I'm a bit confused about the difference between public and private keys in these options. I thought both keys were needed for encryption and decryption, but maybe I'm misremembering.

I practiced a similar question where the roles of public and private keys were mixed up. I feel like option D might be the right one.

I think I remember that public key cryptography involves using a public key for encryption and a private key for decryption, but I'm not sure which option that is.

Hmm, I'm not totally sure about this one. I know public key crypto involves two keys, but I'm not confident I can explain how they're used. I'll have to make an educated guess.

I've got this! Public key cryptography uses a public key to encrypt the message, and the private key to decrypt it. The answer has to be D.

Wait, I'm a bit confused. Isn't public key cryptography about using a pair of keys, one public and one private? I'll have to re-read the question carefully.

Okay, I remember learning about this in class. I'm pretty sure the answer is D - the message is encrypted with the public key and decrypted with the private key.
