The \fB\s-1DER\s0\fR option uses an \s-1ASN1\s0 \s-1DER\s0 encoded +form compatible with the PKCS#3 DHparameter structure. The \s-1PEM\s0 form is the +default format: it consists of the \fB\s-1DER\s0\fR format base64 encoded with +additional header and footer lines. +.IP "\fB\-outform DER|PEM\fR" 4 +.IX Item "-outform DER|PEM" +This specifies the output format, the options have the same meaning as the +\&\fB\-inform\fR option. +.IP "\fB\-in\fR \fIfilename\fR" 4 +.IX Item "-in filename" +This specifies the input filename to read parameters from or standard input if +this option is not specified. +.IP "\fB\-out\fR \fIfilename\fR" 4 +.IX Item "-out filename" +This specifies the output filename parameters to. 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, \s-1DSA\s0 rather than \s-1DH\s0 parameters are read or created; +they are converted to \s-1DH\s0 format. Otherwise, \*(L"strong\*(R" primes (such +that (p\-1)/2 is also prime) will be used for \s-1DH\s0 parameter generation. +.Sp +\&\s-1DH\s0 parameter generation with the \fB\-dsaparam\fR option is much faster, +and the recommended exponent length is shorter, which makes \s-1DH\s0 key +exchange more efficient. Beware that with such DSA-style \s-1DH\s0 +parameters, a fresh \s-1DH\s0 key should be created for each use to +avoid small-subgroup attacks that may be possible otherwise. +.IP "\fB\-2\fR, \fB\-5\fR" 4 +.IX Item "-2, -5" +The generator to use, either 2 or 5. 2 is the default.

It must be the last option. If not present then a value of 512 +is used. If this option is present then the input file is ignored and +parameters are generated instead. +.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 \s-1DH\s0 parameters in human readable form. +.IP "\fB\-C\fR" 4 +.IX Item "-C" +this option converts the parameters into C code.
