3 | =head1 NAME | ||
4 | |||
5 | RAND_bytes, RAND_pseudo_bytes - generate random data | ||
6 | |||
7 | =head1 SYNOPSIS | ||
8 | |||
9 | #include <openssl/rand.h> | ||
10 | |||
11 | int RAND_bytes(unsigned char *buf, int num); | ||
12 | |||
13 | int RAND_pseudo_bytes(unsigned char *buf, int num); | ||
14 | |||
15 | =head1 DESCRIPTION | ||
16 | |||
17 | RAND_bytes() puts B<num> cryptographically strong pseudo-random bytes | ||
18 | into B<buf>. An error occurs if the PRNG has not been seeded with | ||
19 | enough randomness to ensure an unpredictable byte sequence. | ||
20 | |||
21 | RAND_pseudo_bytes() puts B<num> pseudo-random bytes into B<buf>. | ||
22 | Pseudo-random byte sequences generated by RAND_pseudo_bytes() will be | ||
23 | unique if they are of sufficient length, but are not necessarily | ||
24 | unpredictable. They can be used for non-cryptographic purposes and for | ||
25 | certain purposes in cryptographic protocols, but usually not for key | ||
26 | generation etc. | ||
27 | |||
28 | =head1 RETURN VALUES | ||
29 | |||
30 | RAND_bytes() returns 1 on success, 0 otherwise. The error code can be | ||
31 | obtained by L<ERR_get_error(3)|ERR_get_error(3)>. RAND_pseudo_bytes() returns 1 if the | ||
32 | bytes generated are cryptographically strong, 0 otherwise. Both | ||
33 | functions return -1 if they are not supported by the current RAND | ||
34 | method. | ||
35 | |||

41 | =head1 HISTORY | ||
42 | |||
43 | RAND_bytes() is available in all versions of SSLeay and OpenSSL. It | ||
44 | has a return value since OpenSSL 0.9.5. RAND_pseudo_bytes() was added | ||
45 | in OpenSSL 0.9.5. | ||
