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.

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.
