Hi Jeremy,

There has been a recent PR https://github.com/Mbed-TLS/mbedtls/pull/6264 with changes to align with RFC9146. Feel free to comment on the PR. Reviews from the project maintainers/reviewers will happen as they find bandwidth probably before end of the year.

Regards, Shebu

Hi everyone,

I would like to know what is the current support of Mbed TLS regarding the RFC 9146 (https://datatracker.ietf.org/doc/html/rfc9146) published in March 2022.

Mbed TLS is currently supporting a draft version of this RFC (https://datatracker.ietf.org/doc/html/draft-ietf-tls-dtls-connection-id-05) through the define MBEDTLS_SSL_DTLS_CONNECTION_ID, but I just wanted to know the progress on supporting the newly RFC released this year. Are there any plan to support it soon ? If yes, will it be in the coming weeks / months (i.e.: next release) ?

I'm asking since I'm currently playing with the Connection ID on both a DTLS 1.2 Server and DTLS 1.2 Client.

Anyway, have a nice day, Best regards, Jérémy Audiger
