EnvLoader - CLI Tool

EnvLoader is a powerful command-line interface (CLI) tool designed to enhance the management of environment variables in your projects. With the ability to encrypt and decrypt files, EnvLoader also provides seamless injection of environment variables from .ini files into binary files.

Features

• File Encryption and Decryption: Securely encrypt and decrypt files to protect sensitive information.

• Environment Variable Injection into Binary Files: Easily load environment variables from .ini files and inject them into binary files, suitable for Docker Compose and shell scripts.

Usage

Using key prompt:

envLoader encrypt -f config.ini

envLoader decrypt -f config.ini

Using key string:

-k [your secure key]

--key [your secure key]

Using key file:

--key-file [your file with secure key]

Using in-place to the same file:

-i 

--in-place 

Using output to a different file:

-o [file]

--output [file]

Loading variables

EnvLoader allows you to seamlessly load environment variables from both encrypted and decrypted .ini configuration files into shell scripts. This is particularly useful for managing configurations across different environments such as development, testing, and production.

Shell type option can be changed by setting environment variable ENVLOADER_SHELL_TYPE to something like /bin/bash. Default value for this option is /bin/sh.

Assuming simple config.ini file and binary script run.sh:

message="Hello everyone!"

[github]
name=MyFancyNameOnGithub

[gitlab]
name=MyFancyNameOnGitlab

#!/bin/sh

echo "Running! $MESSAGE" >> test.txt
echo "Running! $NAME" >> test.txt

Encrypted configuration

Load Variables from encrypted .ini configuration:

envLoader -f config.ini -b run.sh -k [your secure key] -e github

In this example, the -e flag is used to choose the section (github in this case), and EnvLoader will include variables from both the global section and the specified section in the generated script.

Decrypted configuration

Load Variables from decrypted .ini configuration:

envLoader -f config.ini -b run.sh -e gitlab

Docker Image

You can test envLoader with Docker image.

docker pull kejrak/envloader:latest

docker run --rm kejrak/envloader

Try It Yourself!

Clone the repository, build the application or download it.

make build

Place the binary into your $PATH.

Encrypt it!

Encrypt the configuration file with provided password file and load it's variables into the binary scripts.

cd mock/  
envLoader encrypt -f config.ini --key-file password.txt  
envLoader load -f config.ini -b run.sh --key-file password.txt -e github

Check the created test.txt:

cat test.txt
