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.
