From what I see `SSL_set1_verify_cert_store` & `SSL_set1_chain_cert_store` are available in OpenSSL 1.0.2 (see e.g. https://github.com/openssl/openssl/blob/OpenSSL_1_0_2k/ssl/ssl.h). If we would like to include RHEL7 we should test for `OPENSSL_VERSION_NUMBER >= 0x10002000L`. -- You are receiving this because you are subscribed to this thread.
