according to this thread in wolfssl forum
https://www.wolfssl.com/forums/topic140 ... -pair.html
I should be able to use the function wolfSSL_CTX_check_private_key() to validate the ssl key pairs. I included the header file. and linked to the library cryptolib.a. However I got the undefined reference linker error. Any ideas what's wrong?

Hi RebootExpert,
To use this function, you'll need to undefine NO_FILESYSTEM in nburn\include\crypto\platform\<platform>.h and then rebuild the crypto libraries.
In the next release of our tools, this will be used in the function
, so you'll be able to use that to the same effect if you like.
Kind Regards,
Jon

Hi Jon, I am using MOD54415 and there's only a user_settings.h header file in the directory of C:\nburn\include\crypto\platform\MOD5441X
So I undefine NO_FILESYSTEM in the file. and rebuild the libraries. Same error occur when I try to use it.
There's #ifndef directive check the NO_CERTS macro around the declaration and definition of wolfSSL_CTX_check_private_key()
But NO_CERTS is already undefined by default in user_settings.h

Hi RebootExpert,
Sorry about that, the file you mentioned is the correct one. When you did the rebuild, is that from the command line or through NBEclipse? It shouldn't matter, but I'm just trying to collect as much info as possible. Would it be possible for you to send me your project code and your user_settings.h file?
You can email them directly to me at jcox(at)netburner.com. I'd like to see if I can replicate the issue you're experiencing.
Kind Regards,
Jon

Hi Jon,
I rebuild the libraries through NBEclipse IDE. Here's my simple project I just made having the same error.
Code: Select all
#include <predef.h>
#include <stdio.h>
#include <ctype.h>
#include <startnet.h>
#include <autoupdate.h>
#include <dhcpclient.h>
#include <smarttrap.h>
#include <taskmon.h>
#include <NetworkDebug.h>
#include <crypto/ssl.h>
extern "C" {
void UserMain(void * pd);
}
const char * AppName="validation";
bool validation()
{
WOLFSSL_CTX* ctx = wolfSSL_CTX_new(wolfTLSv1_2_server_method());
int isValid = wolfSSL_CTX_check_private_key(ctx); //undefined reference error
wolfSSL_CTX_free(ctx);
return isValid == WOLFSSL_SUCCESS;
}
void UserMain(void * pd) {
InitializeStack();
GetDHCPAddressIfNecessary();
OSChangePrio(MAIN_PRIO);
EnableAutoUpdate();
StartHTTP();
EnableTaskMonitor();
#ifndef _DEBUG
EnableSmartTraps();
#endif
#ifdef _DEBUG
InitializeNetworkGDB_and_Wait();
#endif
iprintf("Application started\n");
validation();
while (1) {
OSTimeDly(TICKS_PER_SECOND);
}
}

and the header file for MOD5441X

Hey RebootExpert,
When you rebuild the system libraries in NBEclipse, does it list the platform that you've selected for the project during the rebuild, or does it show the CB34EX? This can happen if you select rebuild system libraries without having a project selected.
Just to make certain we're rebuilding the SSL libraries with the correct user_settings.h selected, would you mind trying the following:
Open a command terminal
Type
and make sure it lists your NNDK install directory.
Type
and make sure it lists the MOD5441x. If it doesn't, type
Then navigate to
and type
This will force the library to be rebuilt with the settings using the MOD5441X folder specifically. Finally, go back to your project in NBEclipse and try to rebuild the project only, not the system libraries.
Kind Regards,
Jon

Hello,
I am not sure about 2.9.3 as I don't have anything that old, but in 2.9.4 your application code works for me in nbeclipse with the only change being to comment out the #define #include NO_FILESYSTEM as Jon indicated. Although from the lib compilation you posted, it looks like the libs built, so that part is a bit confusing to me. I'm guessing after that your app still had a link error? Sorry this isn't more helpful, but I do not have access to 2.9.3.
