PKEYPARAM(1SSL) 						      OpenSSL							   PKEYPARAM(1SSL)

NAME

       pkeyparam - public key algorithm parameter processing tool

SYNOPSIS

       openssl pkeyparam [-in filename] [-out filename] [-text] [-noout] [-engine id]

DESCRIPTION

       The pkey command processes public or private keys. They can be converted between various forms and their components printed out.

COMMAND OPTIONS

       -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.

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.
