使用 OpenSSL 的相互认证总是成功的
Mutual authentication always succeeds with OpenSSL
我正在使用openssl 和zmq 编写服务器和客户端。
我的客户端和服务器需要相互验证。
但是在服务器上设置 SSL_CTX_set_verify(ssl_ctx,SSL_VERIFY_FAIL_IF_NO_PEER_CERT,NULL)
之后,无论客户端是否发送证书,握手总是成功的。
此外,SSL_get_peer_certificate(tls->get_ssl_())
return null 和 SSL_get_verify_result(tls->get_ssl_())
return 0 表示 X509_V_OK
.
我现在真的很迷茫,很绝望。有什么建议或更正吗?
这是我的代码的一部分:

来自documentation of SSL_CTX_set_verify:
SSL_VERIFY_FAIL_IF_NO_PEER_CERT
Server mode: if the client did not return a certificate, the TLS/SSL handshake is immediately terminated with a "handshake failure" alert. This flag must be used together with SSL_VERIFY_PEER.
您没有按照文档中的描述将它与 SSL_VERIFY_PEER
一起使用,因此它没有效果。
