BN_rand(3)		     OpenSSL		       BN_rand(3)

NAME
       BN_rand, BN_pseudo_rand - generate pseudo-random number

SYNOPSIS
	#include <openssl/bn.h>

	int BN_rand(BIGNUM *rnd, int bits, int top, int bottom);

	int BN_pseudo_rand(BIGNUM *rnd, int bits, int top, int bottom);

DESCRIPTION
       BN_rand() generates a cryptographically strong pseudo-
       random number of bits bits in length and stores it in rnd.
       If top is true, the two most significant bits of the
       number will be set to 1, so that the product of two such
       random numbers will always have 2*bits length.  If bottom
       is true, the number will be odd.

       BN_pseudo_rand() does the same, but pseudo-random numbers
       generated by this function are not necessarily
       unpredictable. They can be used for non-cryptographic
       purposes and for certain purposes in cryptographic
       protocols, but usually not for key generation etc.

       The PRNG must be seeded prior to calling BN_rand().

RETURN VALUES
       BN_rand() and BN_pseudo_rand() return 1 on success, 0 on
       error.  The error codes can be obtained by
       ERR_get_error(3).

SEE ALSO
       bn(3), err(3), rand(3), RAND_add(3), RAND_bytes(3)

HISTORY
       BN_rand() is available in all versions of SSLeay and
       OpenSSL.	 BN_pseudo_rand() was added in OpenSSL 0.9.5.
