If this argument is not specified then standard output is used.       -passout arg           The passphrase used for the output file.  See openssl-passphrase-options(1).       -aes128, -aes192, -aes256, -aria128, -aria192, -aria256, -camellia128, -camellia192, -camellia256, -des, -des3, -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.       -verbose           Print extra details about the operations being performed.       -rand files, -writerand file           See "Random State Options" in openssl(1) for details.       -engine id           See "Engine Options" in openssl(1).  This option is deprecated.       paramfile           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           openssl-dsaparam(1) command.       -provider name       -provider-path path       -propquery propq           See "Provider Options" in openssl(1), provider(7), and property(7).NOTES       DSA key generation is little more than random number generation so it is much quicker that RSA key generation for example.SEE ALSO       openssl(1), openssl-genpkey(1), openssl-dsaparam(1), openssl-dsa(1), openssl-genrsa(1), openssl-rsa(1)HISTORY       The -engine option was deprecated in OpenSSL 3.0.COPYRIGHT       Copyright 2000-2021 The OpenSSL Project Authors.
