# NAME

openssl-configutl - openssl configuration file helper command

# SYNOPSIS

openssl configutl [-help] [-config filename] [-out filename] [-noheader]

# DESCRIPTION

Real world openssl configuration files with use of the .include directive are quite complex, and there is a need to see the resulting system-wide configuration.

This tool is designed for managing OpenSSL configuration files. Currently it processes a configuration file with possibly complex structure and dumps an effective resulting configuration file, to stdout by default.

# OPTIONS

-help

  Print out a usage message.

-config filename

  The configuration file to deal with. If omitted, the compiled one or the one defined via the OPENSSL_CONF environment variable is used.

-out filename

  The output file to be used instead of stdout.

-noheader

  Don't print information about the original config file to be processed.

# EXAMPLES

Dump the configuration file my.conf processing all .include directives to the file result.conf

     openssl configutl -config my.conf -out result.conf

# SEE ALSO

config(5)

# HISTORY

The configutl command was added in OpenSSL 3.6.
