Hi Kaleb,

The wire format is showing version 0x0303 (v1.2) instead of 0x0304 (v1.3) so I don't think this is a wireshark issue.

Regards,
Karl

I'm even trying with the default client:

examples/client/client -v 4 -l TLS13-AES128-GCM-SHA256 -p 443 -s -h 10.239.34.64

And it still shows a 1.2 record. I'm not sure what I'm missing - also, I'd like to be able to send a 0 length NewSessionTicket in the ClientHello - I'm guessing with wolfSSL_set_SessionTicket(ssl, NULL, 0).

The output of the client is below:

And the following method call in my client:

ctx = wolfSSL_CTX_new(wolfTLSv1_3_client_method())

However, wireshark is still showing the ClientHello being sent with TLS 1.2 (0x0303)

Any ideas?

Hi Kaleb, Thanks for the updates and links - It is working now.

To answer your question about use case, I'm running an experiment, implementing a Needham-Schroeder like protocol with a key server where the client has a PSK relationship with a key server and the key server maintains a cache of short lived RFC5077 tickets it maintains with a server. When a client wants to talk to the server, it requests a ticket from the key server. The key server gives the client a ticket to use with the key server but wraps a key that'll be used for the client-server session. So, I think I'll need to introduce some logic on the server side's wolfSSL_CTX_set_TicketEncCtx() call back in order to unwrap using the key fetched by key_name and then synthesize a CTX using the underlying (now unwrapped) key. If you have any implementation ideas, it's greatly appreciated.

Thanks,
Karl

I configured wolfssl with the following:

./configure --enable-opensslextra --enable-tls13-draft22 --enable-psk CFLAGS="-DWOLFSSL_STATIC_PSK" --enable-oldtls=no

I then used the example code to build: server-psk.c and client-psk-resume.c

The only modification I made to the client was: wolfSSL_CTX_new(wolfTLSv1_2_client_method() -> wolfSSL_CTX_new(wolfTLSv1_3_client_method()

I did this to try to force the client to send a TLS 1.3 Client Hello.

However, wireshark still shows TLS 1.2 (0x0303) for both Record Layer and Handshake Protocol. Furthermore, the psk callback method is never invoked on the server AND the server never sends back a Server Hello.

As this is example code, (with little modification noted above AND it didn't work in it's unmodified version either), I'm assuming that either the code examples are wrong OR wolfssl-3.14.0 is.
