What is public key cryptography?

  1. Public Key Cryptography (PKC) uses two keys, a "public key" and a "private key", to implement an encryption algorithm that doesn't require two parties to first exchange a secret key in order to conduct secure communications

  2. Cryptography method which uses Public key for encryption and de-cryption of the message

  3. Choice 2 is correct

  4. Choice 1 and 2 is correct
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Public key cryptography uses asymmetric key pairs - a public key for encryption and a private key for decryption (or vice versa for digital signatures). This eliminates the need for parties to exchange secret keys before communicating securely. Option B incorrectly suggests the same key is used for both encryption and decryption, which would be symmetric cryptography.
