+=head1 NAME
+gendsa - generate a DSA private key from a set of parameters
+=head1 SYNOPSIS
+B<openssl> B<gendsa>
+[B<-out filename>]
+[B<-rand file...>]
+[B<-writerand file>]
+[B<-engine id>]
+The B<gendsa> command generates a DSA private key from a DSA parameter file
+(which will be typically generated by the B<openssl dsaparam> command).
+=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<-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. A pass phrase is prompted for.
+If none of these options is specified no encryption is used.
+=item B<-rand file...>
+A file or files containing random data used to seed the random number
+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<gendsa>
+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<paramfile>
+This option specifies the DSA parameter file to use. The parameters in this
+file determine the size of the private key. DSA parameters can be generated
+and examined using the B<openssl dsaparam> command.
+=head1 NOTES
+DSA key generation is little more than random number generation so it is
+much quicker that RSA key generation for example.
