| =head1 NAME | |
| rand - generate pseudo-random bytes | |
| =head1 SYNOPSIS | |
| B<openssl rand> | |
| [B<-out> I<file>] | |
| [B<-rand> I<file(s)>] | |
| [B<-base64>] | |
| I<num> | |
| =head1 DESCRIPTION | |
| The B<rand> command outputs I<num> pseudo-random bytes after seeding | |
| the random number generater once. As in other B<openssl> command | |
| line tools, PRNG seeding uses the file I<$HOME/>B<.rnd> or B<.rnd> | |
| in addition to the files given in the B<-rand> option. A new | |
| I<$HOME>/B<.rnd> or B<.rnd> file will be written back if enough | |
| seeding was obtained from these sources. | |
| =head1 OPTIONS | |
| =over 4 | |
| =item B<-out> I<file> | |
| Write to I<file> instead of standard output. | |
| =item B<-rand> I<file(s)> | |
| Use specified file or files or EGD socket (see L<RAND_egd(3)|RAND_egd(3)>) | |
| for seeding the random number generator. | |
| Multiple files can be specified separated by a OS-dependent character. | |
| The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for | |
| all others. | |
| =item B<-base64> | |
| Perform base64 encoding on the output. | |
