     NAME
	  BN_new, BN_init, BN_clear, BN_free, BN_clear_free - allocate
	  and free BIGNUMs

     SYNOPSIS
	   #include <openssl/bn.h>

	   BIGNUM *BN_new(void);

	   void BN_init(BIGNUM *);

	   void BN_clear(BIGNUM *a);

	   void BN_free(BIGNUM *a);

	   void BN_clear_free(BIGNUM *a);

     DESCRIPTION
	  BN_new() allocated and initializes a BIGNUM structure.
	  BN_init() initializes an existing uninitialized BIGNUM.

	  BN_clear() is used to destroy sensitive data such as keys
	  when they are no longer needed. It erases the memory used by
	  a and sets it to the value 0.

	  BN_free() frees the components of the BIGNUM, and if it was
	  created by BN_new(), also the structure itself.
	  BN_clear_free() additionally overwrites the data before the
	  memory is returned to the system.

     RETURN VALUES
	  BN_new() returns a pointer to the BIGNUM. If the allocation
	  fails, it returns NULL and sets an error code that can be
	  obtained by ERR_get_error(3).

	  BN_init(), BN_clear(), BN_free() and BN_clear_free() have no
	  return values.

     SEE ALSO
	  bn(3), ERR_get_error(3)

     HISTORY
	  BN_new(), BN_clear(), BN_free() and BN_clear_free() are
	  available in all versions on SSLeay and OpenSSL.  BN_init()
	  was added in SSLeay 0.9.1b.
