BN_new(3)							     BN_new(3)

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
       The BN_new() function allocates and initializes a BIGNUM structure. The
       BN_init() function initializes an existing uninitialized BIGNUM.

       The  BN_clear() function 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.

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

RETURN VALUES
       The BN_new() function returns a pointer to the BIGNUM. If  the  alloca‐
       tion fails, it returns NULL and sets an error code that can be obtained
       by using ERR_get_error().

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

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