Dear openssl-team and users
Is it possible with OpenSSL 1.1.1k to do a TLS handshake using key
material and certificate based on SM2/SM3/SM4 assuming I somehow got my
hands on such keys/certificates?
I think it is only possible with OpenSSL 3.0 to create them.
After checking the web and the source code of the recent OpenSSL 1.1.1k
version I doubt that this is possible and also did not find any
corresponding cipher suites.
Is this assumption correct or is there a way to do a TLS1.2 or TLS1.3
handshake with the aforementioned algorithms?
You are correct, there are no suitable ciphersuites and it is not
possible to add an SM2 based certificate to an SSL_CTX/SSL.
I am aware that the Chinese “GM/T 0024” protocol is not part of OpenSSL
(yet) based on this github issue:
https://github.com/openssl/openssl/issues/12473

Correct.
