      Question

      Which cryptographic system uses two different keys for

      encryption and decryption?
      A Symmetric key cryptography Correct Answer Incorrect Answer
      B Asymmetric key cryptography Correct Answer Incorrect Answer
      C Hashing Correct Answer Incorrect Answer
      D Digital signatures Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      In asymmetric key cryptography, also known as public key cryptography, a pair of keys is used: a public key for encryption and a private key for decryption. This approach allows secure communication without the need for a shared secret key.
