Hi,
From http://www.openssl.org/docs/crypto/RSA_size.html:
rsa->n must not be NULL.
In your code, it probably is. RSA_new initializes the structure but
doesn't generate a key. Try calling RSA_generate_key() before RSA_size():
http://www.openssl.org/docs/crypto/RSA_generate_key.html
Hope it helps !

Hi everybody, I use openssl-0.9.7i to write a small program
on winxp, VC6.0
-----------------------------------------------------------
#include <stdio.h>

int main( int argc, char* argv[] )
{
RSA *rsa_obj ;
int size ;
CRYPTO_malloc_init() ;
rsa_obj = RSA_new();
size = RSA_size( rsa_obj ) ;
RSA_free(rsa_obj) ;
return 0 ;
}

I have change library option as MD, but error occurs when
calling RSA_size(),
execution error is
Unhandled exception in main.exe(LIBEAY32.DLL):0xC0000005:Access Violation
What this message means ?
