 \*(C` and \*(C' are quotes in nroff, nothing in troff, for use with C<>.

'br\}

 Escape single quotes in literal strings from groff's Unicode transform.

 If the F register is >0, we'll generate index entries on stderr for
 titles (.TH), headers (.SH), subsections (.SS), items (.Ip), and index
 entries marked with X<> in POD. Of course, you'll have to process the
 output yourself in some meaningful fashion.

 Avoid warning from groff about undefined register 'F'.

 NAME
openssl-prime - compute prime numbers
 SYNOPSIS
 Header "SYNOPSIS" \fBopenssl prime
[-help]
[-hex]
[-generate]
[-bits num]
[-safe]
[-provider name]
[-provider-path path]
[-provparam [name:]key=value]
[-propquery propq]
[-checks num]
[number ...]
 DESCRIPTION
 Header "DESCRIPTION" This command checks if the specified numbers are prime.

If no numbers are given on the command line, the -generate flag should
be used to generate primes according to the requirements specified by the
rest of the flags.
 OPTIONS
 Header "OPTIONS"  -help 4
 Item "-help" Display an option summary.
 -hex 4
 Item "-hex" Generate hex output.
 -generate 4
 Item "-generate" Generate a prime number.
 "-bits num" 4
 Item "-bits num" Generate a prime with num bits.
 -safe 4
 Item "-safe" When used with -generate, generates a "safe" prime. If the number
generated is n, then check that \*(C`(\f(CIn-1)/2\*(C' is also prime.
 "-provider name" 4
 Item "-provider name"  0
 "-provider-path path" 4
 Item "-provider-path path"  "-provparam [name:]key=value" 4
 Item "-provparam [name:]key=value"  "-propquery propq" 4
 Item "-propquery propq"
See "Provider Options" in openssl\|(1), provider\|(7), and property\|(7).
 "-checks num" 4
 Item "-checks num" This parameter is ignored.
