PKEYPARAM(1)                 OpenSSL                 PKEYPARAM(1)

NAME

     openssl-pkeyparam, 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.
