155 .IX Header "DESCRIPTION"
156 The \fBpkey\fR command processes public or private keys. They can be converted
157 between various forms and their components printed out.
158 .SH "COMMAND OPTIONS"
159 .IX Header "COMMAND OPTIONS"
160 .IP "\fB\-in filename\fR" 4
161 .IX Item "-in filename"
162 This specifies the input filename to read parameters from or standard input if
163 this option is not specified.
164 .IP "\fB\-out filename\fR" 4
165 .IX Item "-out filename"
166 This specifies the output filename to write parameters to or standard output if
167 this option is not specified.
170 prints out the parameters in plain text in addition to the encoded version.
171 .IP "\fB\-noout\fR" 4
173 do not output the encoded version of the parameters.
174 .IP "\fB\-engine id\fR" 4
175 .IX Item "-engine id"
176 specifying an engine (by its unique \fBid\fR string) will cause \fBpkeyparam\fR
177 to attempt to obtain a functional reference to the specified engine,
178 thus initialising it if needed. The engine will then be set as the default
179 for all available algorithms.
182 Print out text version of parameters:
185 \& openssl pkeyparam \-in param.pem \-text
189 There are no \fB\-inform\fR or \fB\-outform\fR options for this command because only
190 \&\s-1PEM\s0 format is supported because the key type is determined by the \s-1PEM\s0 headers.
