If the server uses TLS1.3 then everything seems to work out... The server side reports: starttls: error:141EC044:SSL routines:tls_construct_server_key_exchange:internal error Client side reports: 140620744139200:error:1416F09F:SSL routines:tls_process_server_certificate:length mismatch:../ssl/...

Next step is to construct - server key exchange message. It is failing over there. The cipher suite chosen needs to prepare server key exchange message and curve selected is MBEDTLS_ECP_DP_SECP521R1. I have enabled the corresponding macro also. The failure is exactly at - "mbedtls_ecdh_gen...

In TLS, everything that's needed to construct the CertificateVerify message can be found in the previous handshake messages. It wasn't the same in SSL, which, in addition to the handshake messages, also required the master secret and a couple of other values known as pad_1 and pad_2 (...
the client computer requests a digital certificate from the server. After the server responds to the request and sends the certificate, the client computer examines it, uses it to encrypt the communication, and proceeds with the normal request-response exchange. However, in a virt...

The term "Forward Secrecy" or "Perfect Forward Secrecy" describes a feature of key-agreement (i.e., key-exchange) methods. That is, the server and client keys are used to negotiate new temporary keys that are used specifically and only for the current communication session. Practically, this...
