What is the difference between TLS 1.2 and TLS 1.3?
Correct! Well done.
Incorrect.
The correct answer is B) TLS 1.3 removes weak ciphers and RSA key exchange, mandates forward secrecy, reduces handshake to 1-RTT (0-RTT possible), and eliminates vulnerable features like renegotiation
B
Correct Answer
TLS 1.3 removes weak ciphers and RSA key exchange, mandates forward secrecy, reduces handshake to 1-RTT (0-RTT possible), and eliminates vulnerable features like renegotiation
Explanation
TLS 1.3 removes MD5/SHA-1, RSA key exchange (no forward secrecy), CBC mode, and compression. Only ephemeral key exchanges (ECDHE/DHE) allowed. 1-RTT handshake (vs 2-RTT for 1.2) improves latency.
