-RAND_bytes, RAND_pseudo_bytes - Generate random data
+RAND_bytes, RAND_pseudo_bytes - generate random data
=head1 SYNOPSIS
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
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. Users should use RAND_bytes() instead.
RAND_pseudo_bytes() puts B<num> pseudo-random bytes into B<buf>.
Pseudo-random byte sequences generated by RAND_pseudo_bytes() will be
unique if they are of sufficient length, but are not necessarily
certain purposes in cryptographic protocols, but usually not for key
generation etc.
+The contents of B<buf> is mixed into the entropy pool before retrieving
+the new pseudo-random bytes unless disabled at compile time (see FAQ).

=head1 RETURN VALUES
RAND_bytes() returns 1 on success, 0 otherwise. The error code can be
-obtained by L<ERR_get_error(3)|ERR_get_error(3)>. RAND_pseudo_bytes() returns 1 if the
+obtained by L<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.
