PKEYPARAM(1SSL) OpenSSL PKEYPARAM(1SSL)
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.
