Ssl_restore_master_key can't find pre-master secret by Unencrypted pre-master secret Trying to use TLS keylog in /tmp/ssl-keys.log ssl_generate_pre_master_secret: found SSL_HND_CLIENT_KEY_EXCHG, state 17 (By the way, you need the server's private key to do this, of course.Please see below debug logs for TLS decryption, I have provided the SSL-key-log file and still error message I get is: The log files will contain the pre-master secret and the shared keys.

(Note that the user interface has changed slightly in newer versions of Wireshark, in the way you configure the private key.) If you follow the instructions about decrypting SSL with Wireshark, use the 'SSL debug file' option to store the logs into a file. (Note that using Ephemeral Diffie-Hellman isn't the only reason for not seeing a server key exchange message: it could also use a DH_DSS or DH_RSA cipher suite, but this is unusual as far as I know). You can see the encrypted pre-master secret when using RSA authenticated key exchange.

You won't see the encrypted shared-key, it's not exchanged.
