I think this was addressed by https://gitlab.com/libssh/libssh-mirror/merge_requests/63 for OpenSSL.

The support should be available also in the mbedTLS and libgcrypt, but the question is whether it makes sense there as the primary backend is openssl here.

I think supporting mbedtls in future would be nice as it is GPL licensed. libgcrypt is just a mess and we should remove it at one point.
