NAME
openssl-dsaparam - DSA parameter manipulation and generation
SYNOPSIS
openssl dsaparam
[-help]
[-inform DER|PEM]
[-outform DER|PEM]
[-in filename]
[-out filename]
[-noout]
[-text]
[-genkey]
[-verbose]
[-rand files]
[-writerand file]
[-engine id]
[-provider name]
[-provider-path path]
[-propquery propq]
[numbits]
DESCRIPTION
This command is used to manipulate or generate DSA parameter files.
DSA parameter generation can be a slow process and as a result the same set of
DSA parameters is often used to generate several distinct keys.
OPTIONS
- -help
-
Print out a usage message.
- -inform DER|PEM
-
The DSA parameters input format; unspecified by default.
See openssl-format-options(1) for details.
- -outform DER|PEM
-
The DSA parameters output format; the default is PEM.
See openssl-format-options(1) for details.
Parameters are a sequence of ASN.1 INTEGERs: p, q, and g.
This is compatible with RFC 2459 DSS-Parms structure.
- -in filename
-
This specifies the input filename to read parameters from or standard input if
this option is not specified. If the numbits parameter is included then
this option will be ignored.
- -out filename
-
This specifies the output filename parameters to. Standard output is used
if this option is not present. The output filename should not be the same
as the input filename.
- -noout
-
This option inhibits the output of the encoded version of the parameters.
- -text
-
This option prints out the DSA parameters in human readable form.
- -genkey
-
This option will generate a DSA either using the specified or generated
parameters.
- -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.
- numbits
-
This option specifies that a parameter set should be generated of size
numbits. It must be the last option. If this option is included then
the input file (if any) is ignored.
- -provider name
-
- -provider-path path
-
- -propquery propq
-
See ``Provider Options'' in openssl(1), provider(7), and property(7).

HISTORY
