=head1 DESCRIPTION
|
||
|
|
|
||
|
|
The B<prime> command checks if the specified numbers are prime.
|
||
|
|
|
||
|
|
If no numbers are given on the command line, the B<-generate> flag should
|
||
|
|
be used to generate primes according to the requirements specified by the
|
||
|
|
rest of the flags.

=head1 OPTIONS
|
||
|
|
|
||
|
|
=over 4
|
||
|
|
|
||
|
|
=item [B<-help>]
|
||
|
|
|
||
|
|
Display an option summary.
|
||
|
|
|
||
|
|
=item [B<-hex>]
|
||
|
|
|
||
|
|
Generate hex output.
|
||
|
|
|
||
|
|
=item [B<-generate>]
|
||
|
|
|
||
|
|
Generate a prime number.
|
||
|
|
|
||
|
|
=item [B<-bits num>]
|
||
|
|
|
||
|
|
Generate a prime with B<num> bits.
|
||
|
|
|
||
|
|
=item [B<-safe>]
|
||
|
|
|
||
|
|
When used with B<-generate>, generates a "safe" prime. If the number
|
||
|
|
generated is B<n>, then check that B<(n-1)/2> is also prime.
|
||
|
|
|
||
|
|
=item [B<-checks num>]
|
||
|
|
|
||
|
|
Perform the checks B<num> times to see that the generated number
|
||
|
|
is prime. The default is 20.
