NAME
openssl-pkeyparam, pkeyparam - public key algorithm parameter processing tool
SYNOPSIS
openssl pkeyparam
[
-help]
[
-in filename]
[
-out filename]
[
-text]
[
-noout]
[
-engine id]
[
-check]
DESCRIPTION
The
pkeyparam command processes public key algorithm parameters.
They can be checked for correctness and their components printed out.
OPTIONS
- -help
-
Print out a usage message.
- -in filename
-
This specifies the input filename to read parameters from or standard input if
this option is not specified.
- -out filename
-
This specifies the output filename to write parameters to or standard output if
this option is not specified.
- -text
-
Prints out the parameters in plain text in addition to the encoded version.
- -noout
-
Do not output the encoded version of the parameters.
- -engine id
-
Specifying an engine (by its unique id string) will cause pkeyparam
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.
- -check
-
This option checks the correctness of parameters.
EXAMPLES
Print out text version of parameters:
openssl pkeyparam -in param.pem -text
NOTES
There are no
-inform or
-outform options for this command because only
PEM format is supported because the key type is determined by the
PEM headers.
