7 | =head1 SYNOPSIS | ||
8 | |||
9 | #include <openssl/rand.h> | ||
10 | |||
11 | void RAND_set_rand_method(RAND_METHOD *meth); | ||
12 | |||

14 | |||
15 | RAND_METHOD *RAND_SSLeay(void); | ||

17 | =head1 DESCRIPTION | ||
18 | |||
19 | A B<RAND_METHOD> specifies the functions that OpenSSL uses for random | ||
20 | number generation. By modifying the method, alternative | ||
21 | implementations such as hardware RNGs may be used. Initially, the | ||
22 | default is to use the OpenSSL internal implementation. RAND_SSLeay() | ||
23 | returns a pointer to that method. | ||
24 | |||
25 | RAND_set_rand_method() sets the RAND method to B<meth>. | ||
26 | RAND_get_rand_method() returns a pointer to the current method. | ||
27 | |||
28 | =head1 THE RAND_METHOD STRUCTURE | ||
29 | |||
30 | typedef struct rand_meth_st | ||
31 | { | ||
32 | void (*seed)(const void *buf, int num); | ||
33 | int (*bytes)(unsigned char *buf, int num); | ||
34 | void (*cleanup)(void); | ||
35 | void (*add)(const void *buf, int num, int entropy); | ||
36 | int (*pseudorand)(unsigned char *buf, int num); | ||
37 | int (*status)(void); | ||
38 | } RAND_METHOD; | ||
39 | |||
40 | The components point to the implementation of RAND_seed(), | ||
41 | RAND_bytes(), RAND_cleanup(), RAND_add(), RAND_pseudo_rand() | ||
42 | and RAND_status(). | ||
43 | Each component may be NULL if the function is not implemented. | ||
44 | |||
45 | =head1 RETURN VALUES | ||
46 | |||
47 | RAND_set_rand_method() returns no value. RAND_get_rand_method() and | ||
48 | RAND_SSLeay() return pointers to the respective methods. | ||

54 | =head1 HISTORY | ||
55 | |||
56 | RAND_set_rand_method(), RAND_get_rand_method() and RAND_SSLeay() are | ||
57 | available in all versions of OpenSSL. | ||
