=head1 NAME
|
|
|
|
RAND_bytes, RAND_pseudo_bytes - generate random data
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/rand.h>
|
|
|
|
int RAND_bytes(unsigned char *buf, int num);
|
|
|
|
Deprecated:
|
|
|
|
#if OPENSSL_API_COMPAT < 0x10100000L
|
|
int RAND_pseudo_bytes(unsigned char *buf, int num);
|
|
#endif
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
RAND_bytes() puts B<num> cryptographically strong pseudo-random bytes
|
|
into B<buf>. An error occurs if the PRNG has not been seeded with
|
|
enough randomness to ensure an unpredictable byte sequence.
|
|
|
|
RAND_pseudo_bytes() has been deprecated; use RAND_bytes() instead.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
RAND_bytes() returns 1 on success, -1 if not supported by the current
|
|
RAND method, or 0 on other failure. The error code can be
|
|
obtained by L<ERR_get_error(3)>.
|
|
|
|
=head HISTORY
|
|
|
|
RAND_pseudo_bytes() was deprecated in OpenSSL 1.1.0.
