证书验证在与boost :: asio和OpenSSL的客户端服务器通信中失败

[英]Certificate verify failed in client server communication with boost::asio and OpenSSL

问题描述

我正在为此编写简单的回显服务器和客户端，以作为通过boost :: asio和OpenSSL进行加密网络通信的概念证明。 我希望双方都使用自签名证书进行身份验证。 我对双方使用相同的私钥，并从中生成了两个证书。 但是，当我尝试在双方之间建立安全通信时，在握手阶段会出现以下错误：

证书验证失败

首先，我使用以下命令生成了私钥和服务器证书： 

openssl req -x509 -newkey rsa:2048 -keyout private_key.pem -out certificate.pem -days 365 -nodes

然后我为客户端生成了其他证书 

 openssl req -newkey rsa:2048 -nodes -keyout private_key.pem -x509 -days 365 -out client_certificate.pem

服务器中OpenSSL上下文的初始化为： 

...
, m_sslContext(ssl::context::sslv23)
...
m_sslContext.set_verify_mode(ssl::verify_peer | ssl::verify_fail_if_no_peer_cert);
m_sslContext.use_private_key_file(options.privateKeyFile, ssl::context::pem);
m_sslContext.use_certificate_file(options.certificateFile, ssl::context::pem);
...

在客户端中是： 

...
, m_sslContext(ssl::context::sslv23)
...
 m_sslContext.set_verify_mode(ssl::verify_peer);
 m_sslContext.use_private_key_file(options.privateKeyFile, ssl::context::pem);
 m_sslContext.use_certificate_file(options.certificateFile, ssl::context::pem);
...

use_certificate_file()和use_private_key_file()允许您向对等方提供公共密钥并解密对等方返回的内容，但是它们不处理验证。 您应该使用add_certificate_authority() ， add_verify_path() ， load_verify_file() ， set_default_verify_paths()和set_verify_callback()一个（或多个set_verify_callback()来配置信任验证。 看起来load_verify_file()可能是您想要的那个。

您似乎误以为私钥用于验证对等证书。 事实并非如此-密钥不用于验证签名，通常客户端和服务器私钥将不同。 CA证书用于验证对等证书。 在您的情况下，因为您使用的是自签名证书，所以CA证书和对等证书是相同的。 双方需要加载对方的证书进行验证。
