       This command processes public key algorithm parameters.  They can be checked for correctness and their
       components printed out.

       Print out text version of parameters:

        openssl pkeyparam -in param.pem -text

       The -engine option was deprecated in OpenSSL 3.0.

       openssl-pkeyparam - public key algorithm parameter processing command

       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.

-help
           Print out a usage message.

       -infilename
           This  specifies  the  input  filename to read parameters from or standard input if this option is not
           specified.

       -outfilename
           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.

       -check
           This option checks the correctness of parameters.

       -engineid
           See "Engine Options" in openssl(1).  This option is deprecated.

       -providername-provider-pathpath-propquerypropq
           See "Provider Options" in openssl(1), provider(7), and property(7).
