OpenSSL 0.9.5 merge
*warning* this bumps shared lib minors for libssl and libcrypto from 2.1 to 2.2
if you are using the ssl26 packages for ssh and other things to work you will
need to get new ones (see ~beck/libsslsnap/<arch>) on cvs or ~beck/src-patent.tar.gz on cvs

4 | |||
5 | RAND_set_rand_method, RAND_get_rand_method, RAND_SSLeay - select RAND method | ||
6 | |||
7 | =head1 SYNOPSIS | ||
8 | |||
9 | #include <openssl/rand.h> | ||
10 | |||
11 | void RAND_set_rand_method(RAND_METHOD *meth); | ||
12 | |||
13 | RAND_METHOD *RAND_get_rand_method(void); | ||
14 | |||
15 | RAND_METHOD *RAND_SSLeay(void); | ||
16 | |||
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 | } RAND_METHOD; | ||
38 | |||
39 | The components point to the implementation of RAND_seed(), | ||
40 | RAND_bytes(), RAND_cleanup(), RAND_add() and RAND_pseudo_rand(). | ||
41 | Each component may be NULL if the function is not implemented. | ||
42 | |||
43 | =head1 RETURN VALUES | ||
44 | |||
45 | RAND_set_rand_method() returns no value. RAND_get_rand_method() and | ||
46 | RAND_SSLeay() return pointers to the respective methods. | ||
47 | |||

51 | |||
52 | =head1 HISTORY | ||
53 | |||
54 | RAND_set_rand_method(), RAND_get_rand_method() and RAND_SSLeay() are | ||
55 | available in all versions of OpenSSL. | ||
