Hello Simon,I started my TLS implementations on LwIP with matrixSSL. At that time I was either using an older LwIP version or I just oversaw the ALTCP layer, so I implemented this completely from scratch. In the meantime I am using mbedTLS (in this case of course TLS 1.2) as I was running into some issues with dropped connections. But with mbedTLS I face exactly the same issue. I guess my CPU (Tiva TM4C129) is too slow.
Nevertheless: comparing the two solutions, matrixSSL is working with TLS 1.3 and I have the feeling that the memory management is more intelligent. With mbedTLS I had to restrict the number of TCP_PCBs to 4 each connection needs a buffer of 16k. With matrixSSL I run 10 TCP_PCBs without this restriction as they allocate the large buffers only for a very restricted time, so I never ran into that issue.

Does anyone have experience delivering TLS V1.3 with LwIP? I understand that the current Mbed library only has V1.2. OpenSSL has V1.3. Can anyone point me to any material about integrating OpenSSL into LwIP? -- Sent from: http://lwip.100.n7.nabble.com/lwip-users-f3.html _______________________________________________ lwip-users mailing list address@hidden https://lists.nongnu.org/mailman/listinfo/lwip-users
