openssl pkeyparam

pkeyparam - public key algorithm parameter processing tool 

openssl command


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.


COMMAND 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.


EXAMPLE

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.
