Hi Ger,
Thank you for your reply. I tried with your suggestion.
The file privateKeyFile was created. The execution goes directly to else part
I also checked the folder including the application and I found the created
file privateKeyFile. The size is 0KB.

I've seen this in a few other circumstances too, but first let's make
absolutely sure the OS allows you to create that file: add a check for
privateKeyFile==NULL _before_ you use that FILE handle - as you should ;-)
So that would mean something along these lines (code from my head, i.e.
untested):
privateKeyFile = fopen("Privatekey", "w");
if (privateKeyFile == NULL)
{
/* might be handy to print the errno value too! */
fprintf(stderr, "Fatal error: cannot create/open file '%s' for writing:
%s\n", "Privatekey", strerror(errno));
exit(EXIT_FAILURE); // abort test app
}
else
{
PEM_write_RSAPrivateKey(privateKeyFile, r,NULL,NULL, 0,NULL, NULL);
...
// don't forget to close the handle:
fclose(privateKeyFile);
}
// done
Hope this helps you along,
Ger

I use VS2005 to create a private RSA key. But I always get the error from the

RSA *r =NULL;
int bits=512;
unsigned long e=RSA_3;
FILE *privateKeyFile;

fopen_s(&privateKeyFile,"Privatekey", "w"); //privateKeyFile =

PEM_write_RSAPrivateKey(privateKeyFile, r,NULL,NULL, 0,NULL, NULL);
The error comes from the function PEM_write_RSAPrivateKey().
Please help me!
