openssl-prime,
prime - compute prime numbers
=head1 SYNOPSIS
B
[B<-help>]
[B<-hex>]
[B<-generate>]
[B<-bits>]
[B<-safe>]
[B<-checks>]
[I]
=head1 DESCRIPTION
The B 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 bits.
=item [B<-safe>]
When used with B<-generate>, generates a "safe" prime. If the number
generated is B, then check that B<(n-1)/2> is also prime.
=item [B<-checks num>]
Perform the checks B times to see that the generated number
is prime. The default is 20.
