An error occurs if the PRNG has not been seeded with -enough randomness to ensure an unpredictable byte sequence. - -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 -unpredictable. They can be used for non-cryptographic purposes and for -certain purposes in cryptographic protocols, but usually not for key -generation etc. - -=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 -bytes generated are cryptographically strong, 0 otherwise. Both -functions return -1 if they are not supported by the current RAND -method. - -=head1 SEE ALSO - -L<rand(3)|rand(3)>, L<ERR_get_error(3)|ERR_get_error(3)>, -L<RAND_add(3)|RAND_add(3)> - -=head1 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. - -=cut |
