OPENSSL-CONFIGUTL(1ossl) OpenSSL OPENSSL-CONFIGUTL(1ossl)
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.
