Question

Explain the difference between asymmetric and symmetric encryption.

Answer 1

Symmetric encryption requires the same key for encryption and decryption. On the other hand, asymmetric encryption needs different keys for encryption and decryption.

Answer 2

The differences between Asymmetric and Symmetric encryption are:

Asymmetric Encryption                                                   Symmetric Encryption 

It uses different keys for encryption and decryption. It requires a single key for both encryption and decryption.

The encryption process is slow.                                The encryption process is very fast.

Asymmetric Encryption offers confidentiality,                 It provides only confidentiality.
authenticity, and non-repudiation.

This is used to transfer a small amount of data.      Symmetric Encryption is used when a large                                                                                        amount of data is required to transfer.
