Add a -provider option to allow providers to be loaded. This option can be specified multiple times. Add a -provider_path option to allow the path to providers to be specified. Reviewed-by: Tomas Mraz <tmraz@fedoraproject.org> (Merged from https://github.com/openssl/openssl/pull/11167)

=head1 DESCRIPTION
|
|
|
|
This command has been deprecated.
|
|
The L<openssl-genpkey(1)> command should be used instead.
|
|
|
|
This command generates an RSA private key.
|
|
|
|
=head1 OPTIONS
|
|
|
|
=over 4
|
|
|
|
=item B<-help>
|
|
|
|
Print out a usage message.
|
|
|
|
=item B<-out> I<filename>
|
|
|
|
Output the key to the specified file. If this argument is not specified then
|
|
standard output is used.
|
|
|
|
=item B<-passout> I<arg>
|
|
|
|
The output file password source. For more information about the format
|
|
see L<openssl(1)/Pass Phrase Options>.
|
|
|
|
=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>, B<-f4>, B<-3>
|
|
|
|
The public exponent to use, either 65537 or 3. The default is 65537.
|
|
|
|
=item B<-primes> I<num>
|
|
|
|
Specify the number of primes to use while generating the RSA key. The I<num>
|
|
parameter must be a positive integer that is greater than 1 and less than 16.
|
|
If I<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.

{- $OpenSSL::safe::opt_provider_item -}
|
|

|
=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.
