SSL_get_verify_result returns irc.freenode.net 的错误 20
SSL_get_verify_result returns Error 20 for irc.freenode.net
我正在尝试根据 UTN_USERFirst_Hardware CA 验证 IRC 服务器的证书。
我 运行 从 SSL_get_verify_result 进入错误代码 20（如果我是正确的，这意味着它未能获得对等证书？）。
另外，我不太确定 'steps' 在这个过程中的优先级是什么。
这是我拼凑的：

上下文的调用例程：
int main(int argc, char *argv[])
{
tallis_t *tallis = malloc(sizeof(tallis_t));
tallis->host = "irc.freenode.net";
tallis->port = "6697";
tallis->bio = NULL;
tallis->ssl_connection = NULL;
ssl_init(tallis->ssl_connection);
tallis->ssl_context = SSL_CTX_new(TLSv1_2_client_method());
tallis->ssl_connection = SSL_new(tallis->ssl_context);
tallis->param = SSL_get0_param(tallis->ssl_connection);
int rv;
rv = tallis_connect(tallis);
if (rv)
DIE("%s\n", "connection failed");
ERR_clear_error();
X509 *cert = SSL_get_peer_certificate(tallis->ssl_connection);
if (!cert)
DIE("%s\n", ERR_error_string(ERR_get_error(), NULL));
rv = tallis_ssl_verify(tallis, cert);
X509_free(cert);
if (rv)
DIE("%s\n", "certificate verificiation failed");
else
printf("%s\n", "certificate verification succeeded");
rv = tallis_loop(tallis);
if (rv)
DIE("%s\n", "socket connection terminated");
rv = ssl_shutdown(tallis);
if (rv)
DIE("%s\n", "ssl shutdown failed");
}
因此，目前我的流程是这样的：在套接字 (BIO) 级别建立连接 -> 调用 SSL_get_peer_certificate -> 进行证书验证，这样正确吗？
SSL_get_verify_result和X509_verify_cert有什么区别，应该先用哪个？
抱歉，如果这太笼统了，我需要一些指导，文档只是没有太多相关信息的手册页，我发现很难有条理地了解 OpenSSL。
