This command generates a DSA private key from a DSA parameter file (which will
be typically generated by the
openssl-dsaparam(1) command).
- -help
- Print out a usage message.
-
-out filename
- Output the key to the specified file. 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.
Note that all options must be given before the paramfile argument.
Otherwise they are ignored.
- -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).
DSA key generation is little more than random number generation so it is much
quicker that RSA key generation for example.
