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.
