Q4 / 100
What is the difference between symmetric and asymmetric encryption?
Correct! Well done.
Incorrect.
The correct answer is B) Symmetric uses the same key for encrypt and decrypt (fast); asymmetric uses public/private key pairs (slower but solves key distribution)
B
Correct Answer
Symmetric uses the same key for encrypt and decrypt (fast); asymmetric uses public/private key pairs (slower but solves key distribution)
Explanation
Symmetric (AES, ChaCha20): fast, same key both ways — key distribution is the challenge. Asymmetric (RSA, ECC): public key encrypts/verifies; private key decrypts/signs. TLS uses both: asymmetric for key exchange, symmetric for data.
