.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \fBpkey\fR command processes public or private keys. They can be converted
between various forms and their components printed out.
.SH "COMMAND OPTIONS"
.IX Header "COMMAND OPTIONS"
.IP "\fB\-in filename\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 filename\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\-engine id\fR" 4
.IX Item "-engine id"
specifying an engine (by its unique \fBid\fR string) will cause \fBpkeyparam\fR
to attempt to obtain a functional reference to the specified engine,
thus initialising it if needed. The engine will then be set as the default
for all available algorithms.
.SH "EXAMPLE"
.IX Header "EXAMPLE"
Print out text version of parameters:

.SH "NOTES"
.IX Header "NOTES"
There are no \fB\-inform\fR or \fB\-outform\fR options for this command because only
\&\s-1PEM\s0 format is supported because the key type is determined by the \s-1PEM\s0 headers.
