SSL_connect(ssl); // 建立SSL连接 ``` 步骤6:验证SSL证书 在建立SSL连接后,需要验证服务器的SSL证书。 ```c if (SSL_get_verify_result(ssl) != X509_V_OK) { printf("Certificate verification failed\n"); } ``` 步骤7:完成SSL连接 最后,完成SSL连接并进行数据传输操作。 ```c char send_buf[...

Theshowcertsflag appended onto the openssl s_client connect command prints out and will show the entire certificate chain in PEM format, whereas leaving offshowcertsonly prints out and shows the end entity certificate in PEM format. Other than that one difference, the output is the same. The ...
Get SSL server certificate from Server with Openssl s_client Exploring SSL Connection with OpenSSL S_client Command SSL证书意义: 认证服务:确认当前访问的网页是其声明的网页。 数据完整性服务:确认互相传输的数据没有被修改过。 数据保密性服务:即数据的加密,没有密钥的第三方无法获知数据的具体内容。
序列号:由CA给予每一个证书分配的唯一的数字型编号,当证书被取消时,实际上是将此证书序列号放入由CA签发的CRL(Certificate Revocation List证书作废表,或证书黑名单表)中。这也是序列号唯一的原因 签名算法标识符:用来指定CA签署证书时所使用的签名算法,常见算法如RSA ...
intSSL_connect(SSL *ssl); intSSL_accept(SSL *ssl); 握手过程完成之后,Client通常会要求Server发送证书信息,以便对Server进行鉴别。其实现会用到以下两个函数: [cpp]view plaincopyprint? X509 *SSL_get_peer_certificate(SSL *ssl);//从SSL套接字中获取对方的证书信息 ...
Verify return code: 20 (unable to get local issuer certificate) 这些错误表明 openssl s_client 无法使用你提供的根证书来验证服务器证书。 5. 根据验证结果,判断服务器证书的有效性 根据openssl s_client 的输出,你可以判断服务器证书是否有效。如果验证通过(Verify return code: 0 (ok)),则表明服务器证书...
