Shell Programming and Scripting

Hi,
./build-key is a script shell that use openssl...
you can copy and modify this script to add option -subj to fill your fields.
in man req :
You can too modify config file to set param prompt at 'no':
Regards.

Thanks for your reply, but I want to avoid to edit the script, I look for another solution in my side and if someone has another way, with peasure

You could make your system less secure by installing the expect brute force hacking tool, learn its new programming language, and use it to fool openssl into believing it's talking to a real terminal.

Or you can make a minor edit to ./build-key so you can feed in a noninteractive argument the way openssl is designed to handle them.

Your choice.

May be a trick if your script build_key use the variable KEY_CONFIG:
Before to launch the script build_key, just add 2 lines:

Code:

KEY_CONFIG="/etc/openvpn/easy-rsa/openssl-1.0.0.cnf -batch"
export KEY_CONFIG

This trick set -batch option to openssl commande that use this variable without to modify build_key script.

Regards.

another idea that depends on how the build-key script invokes the openssl command.
If it is invoked via the PATH, just in this case create a script called "openssl" that will invoke the real openssl with an additional parameter (-batch) for example.
In your script:

Code:

PATH=path_of_your_script_openssl:$PATH
build-key "$username"
PATH=${PATH#*:}

And script openssl might look like:

Code:

#!/bin/bash
PATH=${PATH#*:}
openssl $@ -batch
exit $?
