Standard output is used +if this option is not present. The output filename should \fBnot\fR be the same +as the input filename. +.IP \fB\-dsaparam\fR 4 +.IX Item "-dsaparam" +If this option is used, DSA rather than DH parameters are read or created; +they are converted to DH format. Otherwise, safe primes (such +that (p\-1)/2 is also prime) will be used for DH parameter generation. +.Sp +DH parameter generation with the \fB\-dsaparam\fR option is much faster. +Beware that with such DSA-style DH parameters, a fresh DH key should be +created for each use to avoid small-subgroup attacks that may be possible +otherwise. +.IP \fB\-check\fR 4 +.IX Item "-check" +Performs numerous checks to see if the supplied parameters are valid and +displays a warning if not. +.IP "\fB\-2\fR, \fB\-3\fR, \fB\-5\fR" 4 +.IX Item "-2, -3, -5" +The generator to use, either 2, 3 or 5. If present then the +input file is ignored and parameters are generated instead. If not +present but \fInumbits\fR is present, parameters are generated with the +default generator 2. +.IP \fInumbits\fR 4 +.IX Item "numbits" +This option specifies that a parameter set should be generated of size +\&\fInumbits\fR. It must be the last option. If this option is present then +the input file is ignored and parameters are generated instead. If +this option is not present but a generator (\fB\-2\fR, \fB\-3\fR or \fB\-5\fR) is +present, parameters are generated with a default length of 2048 bits. +The minimum length is 512 bits. The maximum length is 10000 bits. +.IP \fB\-noout\fR 4 +.IX Item "-noout" +This option inhibits the output of the encoded version of the parameters. +.IP \fB\-text\fR 4 +.IX Item "-text" +This option prints out the DH parameters in human readable form. +.IP "\fB\-engine\fR \fIid\fR" 4 +.IX Item "-engine id" +See "Engine Options" in \fBopenssl\fR\|(1). +This option is deprecated. +.IP "\fB\-rand\fR \fIfiles\fR, \fB\-writerand\fR \fIfile\fR" 4 +.IX Item "-rand files, -writerand file" +See "Random State Options" in \fBopenssl\fR\|(1) for details. +.IP "\fB\-provider\fR \fIname\fR" 4 +.IX Item "-provider name" +.PD 0 +.IP "\fB\-provider\-path\fR \fIpath\fR" 4 +.IX Item "-provider-path path" +.IP "\fB\-propquery\fR \fIpropq\fR" 4 +.IX Item "-propquery propq" +.PD +See "Provider Options" in \fBopenssl\fR\|(1), \fBprovider\fR\|(7), and \fBproperty\fR\|(7). +.IP \fB\-verbose\fR 4 +.IX Item "-verbose" +This option enables the output of progress messages, which is handy when +running commands interactively that may take a long time to execute. +.IP \fB\-quiet\fR 4 +.IX Item "-quiet" +This option suppresses the output of progress messages, which may be +undesirable in batch scripts or pipelines. +.SH NOTES +.IX Header "NOTES" +This command replaces the \fBdh\fR and \fBgendh\fR commands of previous +releases. +.SH "SEE ALSO" +.IX Header "SEE ALSO" +\&\fBopenssl\fR\|(1), +\&\fBopenssl\-pkeyparam\fR\|(1), +\&\fBopenssl\-dsaparam\fR\|(1), +\&\fBopenssl\-genpkey\fR\|(1). +.SH HISTORY +.IX Header "HISTORY" +The \fB\-engine\fR option was deprecated in OpenSSL 3.0. +.PP +The \fB\-C\fR option was removed in OpenSSL 3.0. +.SH COPYRIGHT +.IX Header "COPYRIGHT" +Copyright 2000\-2023 The OpenSSL Project Authors.
