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。
此外,SSL_get_peer_certificate(tls->get_ssl_())
返回 null,SSL_get_verify_result(tls->get_ssl_())
返回 0,这意味着 X509_V_OK
.
我现在真的很迷茫,很绝望。有什么建议或更正吗?
这是我的部分代码:
OpenSSL_add_all_algorithms();
SSL_library_init();
SSL_load_error_strings();
ERR_load_BIO_strings();
const SSL_METHOD *meth;
SSL_CTX *ssl_ctx;
//**************************part of client************************
{
meth = SSLv23_client_method();
ssl_ctx = SSL_CTX_new(meth);
SSL_CTX_set_verify(ssl_ctx,SSL_VERIFY_PEER,NULL);
int rc1 = SSL_CTX_load_verify_locations(ssl_ctx, ".\\demoCA\\private\\server_chain.pem",".\\demoCA\\private\\");///
SSL_CTX_set_default_passwd_cb_userdata(ssl_ctx,"pw");
std::string cert_chain(".\\demoCA\\private\\client_chain.pem");
std::string cert(".\\demoCA\\private\\client_crt.pem");
std::string key(".\\demoCA\\private\\client_key.pem");
int code = SSL_CTX_use_certificate_chain_file(ssl_ctx,cert_chain.c_str());
if (code != 1)
{
std::cout<<"error1\n";
//throw TLSException("failed to read credentials.");
}
code = SSL_CTX_use_PrivateKey_file(ssl_ctx,key.c_str(),SSL_FILETYPE_PEM);
i f (code != 1)
{
std::cout<<"error2\n";
//throw TLSException("failed to read credentials.");
}
if(!SSL_CTX_check_private_key(ssl_ctx))
{
std::cout<<"key wrong";
system("pause");
exit(0);
}
}
//*****************part of server****************************
{
meth = SSLv23_server_method();
ssl_ctx = SSL_CTX_new(meth);
SSL_CTX_set_verify(ssl_ctx,SSL_VERIFY_FAIL_IF_NO_PEER_CERT,NULL)
SSL_CTX_set_client_CA_list(ssl_ctx,SSL_load_client_CA_file(".\\demoCA\\private\\client_chain.pem"));//
SSL_CTX_set_default_passwd_cb_userdata(ssl_ctx,"pw");
std::string cert_chain(".\\demoCA\\private\\server_chain.pem");
std::string cert(".\\demoCA\\private\\server_crt.pem");
std::string key(".\\demoCA\\private\\server_key.pem");
int rc = SSL_CTX_use_certificate_file(ssl_ctx,cert.c_str(),SSL_FILETYPE_PEM);
if (rc!=1)
{
//throw TLSException("failed to read credentials.");
std::cout<<"error1\n";
}
rc = SSL_CTX_use_PrivateKey_file(ssl_ctx,key.c_str(),SSL_FILETYPE_PEM);
if (rc!=1)
{
//throw TLSException("failed to read credentials.");
std::cout<<"error2\n";
}
int rcode = SSL_CTX_check_private_key(ssl_ctx);
if(rcode!=1)
{
std::cout<<"key wrong";
system("pause");
//exit(0);
}
}
最佳答案
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,因此它没有任何效果。
