[openssl-users] using NULL ciphers

I'm trying to use NULL cipher such as ECDHE-ECDSA-NULL-SHA for debugging
purpose. With OpenSSL version 1.0.2p, I was able to make it work. However
with version 1.1.0i or 1.1.1 prev 9, SSL_CTX_set_cipher_list(ctx,
"ECDHE-ECDSA-NULL-SHA") succeeded but SSL_Connect () failed. Is there any
way to enable NULL ciphers with version 1.1.0i or later?
