没有可用自签名证书的对等证书

Question

我正在写一个接受SSL连接的服务器。我已经生成的自签名证书：

openssl req -new -x509 -days 365 -nodes -out self.pem -keyout self.pem -subj "/CN=myhostname" 

SSL_accept失败，此消息：

140121764049248:error:1408A0C1:SSL routines:ssl3_get_client_hello:no shared cipher:s3_srvr.c:1417: 

这里是服务器代码的一部分：

sslCtx = (SSL_CTX_new(SSLv23_server_method()); 
    if (!sslCtx){ 
     ERR_print_errors_fp(stderr); 
    throw runtime_error("SSL_CTX_new failed"); 
    } 
    ssl = SSL_new(sslCtx); 
    if (!ssl) 
    throw runtime_error("SSL_new failed"); 

    if (SSL_CTX_use_PrivateKey_file(sslCtx, keyFile.c_str(), 
            SSL_FILETYPE_PEM) != 1) 
    throw runtime_error("Unable to load private key file" + keyFile); 

    if (SSL_CTX_use_certificate_file(sslCtx, certFile.c_str(), 
            SSL_FILETYPE_PEM) != 1) 
    throw runtime_error("Unable to load certificate file" + certFile); 


    if (SSL_set_fd(ssl, socket) != 1) 
    throw runtime_error("SSL_set_fd failed"); 

    if (SSL_accept(ssl) != 1){ 
    ERR_print_errors_fp(stderr); 
    throw runtime_error("SSL_accept failed"); 
    } 

我试图测试服务器：

openssl s_client -cipher RSA -connect myhostname:33221 -tls1 -CApath . -servername myhostname 

并得到了

我使用的是OpenSSL 1.0.2g。

Answer 1

尝试SSL_new，只有在完全设置上下文并确保在程序开始时有OpenSSL_add_ssl_algorithms。 1.0.2文档说它“继承”，但不确定这是否意味着它在当时复制了设置，并且未应用进一步的更改。

https://www.openssl.org/docs/man1.0.2/ssl/SSL_new.html

新的结构继承底层上下文CTX的设置：连接方法（的SSLv2/V3 /使用TLSv1），选项，验证设定，超时设置。

还有对OpenSSL wiki

一个例子没有错误处理的线沿线的云：

// General initialisation 
SSL_load_error_strings(); 
OpenSSL_add_ssl_algorithms(); 
// Context for a server socket 
ctx = SSL_CTX_new(SSLv23_server_method()); //Note SSLv23_server_method in example is deprecated in favour of TLS_server_method for new versions. TLSv1_2_server_method will force TLS 1.2. 
SSL_CTX_set_ecdh_auto(ctx, 1); 
SSL_CTX_use_certificate_file(ctx, "cert.pem", SSL_FILETYPE_PEM); 
SSL_CTX_use_PrivateKey_file(ctx, "key.pem", SSL_FILETYPE_PEM); 
// Only after all certificates, and other config is set 
ssl = SSL_new(ctx); 
SSL_set_fd(ssl, client_socket); 
SSL_accept(ssl); 
// Use SSL_write and SSL_read 
SSL_free(ssl); 
close(client_socket); 
// OpenSSL cleanup 
EVP_cleanup();
