rand_bytes
RAND_bytes(3openssl) OpenSSL RAND_bytes(3openssl)
NAME
RAND_bytes, RAND_pseudo_bytes - generate random data
SYNOPSIS
#include <openssl/rand.h>
int RAND_bytes(unsigned char *buf, int num);
int RAND_pseudo_bytes(unsigned char *buf, int num);
DESCRIPTION
RAND_bytes() puts num cryptographically strong pseudo-random bytes into buf. An error occurs if the PRNG has not been seeded with enough
randomness to ensure an unpredictable byte sequence.
RAND_pseudo_bytes() puts num pseudo-random bytes into buf. Pseudo-random byte sequences generated by RAND_pseudo_bytes() will be unique if
they are of sufficient length, but are not necessarily unpredictable. They can be used for non-cryptographic purposes and for certain pur-
poses in cryptographic protocols, but usually not for key generation etc.
RETURN VALUES
RAND_bytes() returns 1 on success, 0 otherwise. The error code can be obtained by ERR_get_error(3). RAND_pseudo_bytes() returns 1 if the
bytes generated are cryptographically strong, 0 otherwise. Both functions return -1 if they are not supported by the current RAND method.
SEE ALSO
rand(3), ERR_get_error(3), RAND_add(3)
HISTORY
RAND_bytes() is available in all versions of SSLeay and OpenSSL. It has a return value since OpenSSL 0.9.5. RAND_pseudo_bytes() was added
in OpenSSL 0.9.5.
OpenSSL-0.9.8 Oct 11 2005 RAND_bytes(3openssl)
