CompTIA Security+ SY0-701 Practice Question

Asymmetric encryption uses two related keys—a public key and a private key. This key pair allows for secure communication without the need to share secret keys beforehand. One key encrypts the data, and the other decrypts it, effectively solving the key distribution problem inherent in symmetric encryption. In contrast, symmetric encryption uses a single shared key, which must be securely distributed to all parties beforehand.
