NAME

       openssl-pkeyparam, pkeyparam - public key algorithm parameter process-
       ing tool

SYNOPSIS

       openssl pkeyparam [-in filename] [-out filename] [-text] [-noout]
       [-engine id]

DESCRIPTION

       The pkey command processes public or private keys. They can be con-
       verted between various forms and their components printed out.

COMMAND OPTIONS

       -in filename
           This specifies the input filename to read parameters from or stan-
           dard input if this option is not specified.

       -out filename
           This specifies the output filename to write parameters to or stan-
           dard 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.
