 | =head1 NAME | 
 |  | 
 | openssl-prime, | 
 | prime - compute prime numbers | 
 |  | 
 | =head1 SYNOPSIS | 
 |  | 
 | B<openssl prime> | 
 | [B<-help>] | 
 | [B<-hex>] | 
 | [B<-generate>] | 
 | [B<-bits>] | 
 | [B<-safe>] | 
 | [B<-checks>] | 
 | [I<number...>] | 
 |  | 
 | =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. |
