-=head1 DESCRIPTION
-
-The B<genrsa> command generates an RSA private key.
-
-=head1 OPTIONS
-
-=over 4
-
-=item B<-help>
-
-Print out a usage message.
-
-=item B<-out filename>
-
-Output the key to the specified file. If this argument is not specified then
-standard output is used.
-
-=item B<-passout arg>
-
-The output file password source. For more information about the format
-of B<arg> see the B<PASS PHRASE ARGUMENTS> section in L<openssl(1)>.
-
-=item B<-aes128>, B<-aes192>, B<-aes256>, B<-aria128>, B<-aria192>, B<-aria256>, B<-camellia128>, B<-camellia192>, B<-camellia256>, B<-des>, B<-des3>, B<-idea>
-
-These options encrypt the private key with specified
-cipher before outputting it. If none of these options is
-specified no encryption is used. If encryption is used a pass phrase is prompted
-for if it is not supplied via the B<-passout> argument.
-
-=item B<-F4|-3>
-
-The public exponent to use, either 65537 or 3. The default is 65537.
-
-=item B<-rand file...>
-
-A file or files containing random data used to seed the random number
-generator.
-Multiple files can be specified separated by an OS-dependent character.
-The separator is B<;> for MS-Windows, B<,> for OpenVMS, and B<:> for
-all others.
-
-=item [B<-writerand file>]
-
-Writes random data to the specified I<file> upon exit.
-This can be used with a subsequent B<-rand> flag.
-
-=item B<-engine id>
-
-Specifying an engine (by its unique B<id> string) will cause B<genrsa>
-to attempt to obtain a functional reference to the specified engine,
-thus initialising it if needed. The engine will then be set as the default
-for all available algorithms.
-
-=item B<-primes num>
-
-Specify the number of primes to use while generating the RSA key. The B<num>
-parameter must be a positive integer that is greater than 1 and less than 16.
-If B<num> is greater than 2, then the generated key is called a 'multi-prime'
-RSA key, which is defined in RFC 8017.
-
-=item B<-verbose>
-
-Print extra details about the operations being performed.
-
-=item B<numbits>
-
-The size of the private key to generate in bits. This must be the last option
-specified. The default is 2048 and values less than 512 are not allowed.

-=head1 NOTES
-
-RSA private key generation essentially involves the generation of two or more
-prime numbers. When generating a private key various symbols will be output to
-indicate the progress of the generation. A B<.> represents each number which
-has passed an initial sieve test, B<+> means a number has passed a single
-round of the Miller-Rabin primality test, B<*> means the current prime starts
-a regenerating progress due to some failed tests. A newline means that the number
-has passed all the prime tests (the actual number depends on the key size).
-
-Because key generation is a random process the time taken to generate a key
-may vary somewhat. But in general, more primes lead to less generation time
-of a key.
