YOu should always look at the errors generated by popping
up the error stack like this:
#include "/usr/local/ssl/include/err.h"
if (some_OpenSSL_function_returned_unexpected_results) {
printf("OpenSSL_function failed\n");
while ((ERR_no = ERR_get_error()))
printf("%s\n", ERR_error_string(ERR_no, NULL));
return(-1);
}
To answer your question it would be interesting which
padding method (last parameter of the encrypt function)
do you use and how long your RSA modulus is.
