1=pod 2 3=head1 NAME 4 5rand - generate pseudo-random bytes 6 7=head1 SYNOPSIS 8 9B<openssl rand> 10[B<-out> I<file>] 11[B<-rand> I<file(s)>] 12[B<-base64>] 13I<num> 14 15=head1 DESCRIPTION 16 17The B<rand> command outputs I<num> pseudo-random bytes after seeding 18the random number generator once. As in other B<openssl> command 19line tools, PRNG seeding uses the file I<$HOME/>B<.rnd> or B<.rnd> 20in addition to the files given in the B<-rand> option. A new 21I<$HOME>/B<.rnd> or B<.rnd> file will be written back if enough 22seeding was obtained from these sources. 23 24=head1 OPTIONS 25 26=over 4 27 28=item B<-out> I<file> 29 30Write to I<file> instead of standard output. 31 32=item B<-rand> I<file(s)> 33 34Use specified file or files or EGD socket (see L<RAND_egd(3)|RAND_egd(3)>) 35for seeding the random number generator. 36Multiple files can be specified separated by a OS-dependent character. 37The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for 38all others. 39 40=item B<-base64> 41 42Perform base64 encoding on the output. 43 44=back 45 46=head1 SEE ALSO 47 48L<RAND_bytes(3)|RAND_bytes(3)> 49 50=cut 51
