.SH DESCRIPTION
.IX Header "DESCRIPTION"
This command processes public key algorithm parameters.
They can be checked for correctness and their components printed out.
.SH OPTIONS
.IX Header "OPTIONS"
.IP \fB\-help\fR 4
.IX Item "-help"
Print out a usage message.
.IP "\fB\-in\fR \fIfilename\fR" 4

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 to write parameters to or standard output if
this option is not specified.
.IP \fB\-text\fR 4
.IX Item "-text"
Prints out the parameters in plain text in addition to the encoded version.
.IP \fB\-noout\fR 4
.IX Item "-noout"
Do not output the encoded version of the parameters.
.IP \fB\-check\fR 4
.IX Item "-check"
This option checks the correctness of parameters.
.IP "\fB\-engine\fR \fIid\fR" 4
.IX Item "-engine id"
See "Engine Options" in \fBopenssl\fR\|(1).
This option is deprecated.
.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).
.SH EXAMPLES
.IX Header "EXAMPLES"
Print out text version of parameters:
.PP
.Vb 1
\& openssl pkeyparam \-in param.pem \-text
.Ve
.SH NOTES
.IX Header "NOTES"
There are no \fB\-inform\fR or \fB\-outform\fR options for this command because only
PEM format is supported because the key type is determined by the PEM headers.
