Understanding Asymmetric vs. Symmetric Encryption

Focus Keyword: Asymmetric vs. Symmetric Encryption

Asymmetric encryption, also known as public-key encryption, involves the use of a pair of keys: a public key and a private key. The public key is shared freely and used for encryption, while the private key is kept secret and used for decryption. This system allows for secure communication between parties without the need to exchange secret keys.

Symmetric encryption, on the other hand, uses the same key for both encryption and decryption. This key must be kept secret and shared between parties beforehand. While symmetric encryption is faster and more efficient than asymmetric encryption, it requires a secure method for key exchange.

In summary, the main difference between asymmetric and symmetric encryption lies in the number of keys used and how they are managed. Asymmetric encryption uses a pair of keys, while symmetric encryption uses a single key shared between parties.
