PKEYPARAM(1)                                                 OpenSSL                                                PKEYPARAM(1)



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.
