By modifying the method, alternative -implementations such as hardware RNGs may be used. Initially, the -default is to use the OpenSSL internal implementation. RAND_SSLeay() -returns a pointer to that method. - -RAND_set_rand_method() sets the RAND method to B<meth>. -RAND_get_rand_method() returns a pointer to the current method. - -=head1 THE RAND_METHOD STRUCTURE - - typedef struct rand_meth_st - { - void (*seed)(const void *buf, int num); - int (*bytes)(unsigned char *buf, int num); - void (*cleanup)(void); - void (*add)(const void *buf, int num, int entropy); - int (*pseudorand)(unsigned char *buf, int num); - int (*status)(void); - } RAND_METHOD; - -The components point to the implementation of RAND_seed(), -RAND_bytes(), RAND_cleanup(), RAND_add(), RAND_pseudo_rand() -and RAND_status(). -Each component may be NULL if the function is not implemented. - -=head1 RETURN VALUES - -RAND_set_rand_method() returns no value.
