       RSA_generate_key - generate RSA key pair

	#include <openssl/rsa.h>

	RSA *RSA_generate_key(int num, unsigned long e,
	   void (*callback)(int,int,void *), void *cb_arg);

       RSA_generate_key() generates a key pair and returns it in a newly allocated RSA structure.
       The pseudo-random number generator must be seeded prior to calling RSA_generate_key().

       The modulus size will be num bits, and the public exponent will be e. Key sizes with num <
       1024 should be considered insecure.  The exponent is an odd number, typically 3, 17 or

       A callback function may be used to provide feedback about the progress of the key genera-
       tion. If callback is not NULL, it will be called as follows:

       o   While a random prime number is generated, it is called as described in BN_gener-

       o   When the n-th randomly generated prime is rejected as not suitable for the key, call-
	   back(2, n, cb_arg) is called.

       o   When a random p has been found with p-1 relatively prime to e, it is called as call-
	   back(3, 0, cb_arg).

       The process is then repeated for prime q with callback(3, 1, cb_arg).

       If key generation fails, RSA_generate_key() returns NULL; the error codes can be obtained
       by ERR_get_error(3).

       callback(2, x, cb_arg) is used with two different meanings.

       RSA_generate_key() goes into an infinite loop for illegal input values.

       The cb_arg argument was added in SSLeay 0.9.0.
