Test understanding of public-key cryptography fundamentals, including asymmetric key pairs (generation and properties), common key-exchange methods (Diffie-Hellman, ECDH), how TLS uses public-key mechanisms and certificates for secure handshakes, and how digital signatures (RSA, ECDSA) provide integrity and non-repudiation; assess conceptual knowledge, protocol flow, and basic security considerations such as MITM and certificate validation.
