=pod =head1 NAME openssl-gendsa, gendsa - generate a DSA private key from a set of parameters =head1 SYNOPSIS B B [B<-help>] [B<-out filename>] [B<-aes128>] [B<-aes192>] [B<-aes256>] [B<-aria128>] [B<-aria192>] [B<-aria256>] [B<-camellia128>] [B<-camellia192>] [B<-camellia256>] [B<-des>] [B<-des3>] [B<-idea>] [B<-rand file...>] [B<-writerand file>] [B<-engine id>] [B] =head1 DESCRIPTION The B command generates a DSA private key from a DSA parameter file (which will be typically generated by the B 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 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 upon exit. This can be used with a subsequent B<-rand> flag. =item B<-engine id> Specifying an engine (by its unique B string) will cause B 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 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 command. =back =head1 NOTES DSA key generation is little more than random number generation so it is much quicker that RSA key generation for example. =head1 SEE ALSO L, L, L, L =head1 COPYRIGHT Copyright 2000-2017 The OpenSSL Project Authors.
