Env-Tool is a command line interface program that allows you to securely manage environment variables. The tool provides the ability to encrypt environment variables in JSON format and output a dotenv-compatible .env file.

• Encrypt environment variables in JSON format to a dotenv-compatible .env file.
• Decrypt a .env file back to the original JSON format.
• Generate RSA public and private keys for use in the encryption and decryption process.

• OpenSSL installation is required to generate RSA public and private keys.

Env-Tool provides the following commands:

env-tool encrypt[--encrypt] input-path[env.json] public-key-path output-path[.env]

env-tool decrypt[--decrypt] input-path[.env] private-key-path output-path[env.json]

env-tool keygen[--keygen] output-dir[.keys]

To generate an encrypted .env file from a env.json file:

env-tool encrypt[--encrypt] ./env.json ./.keys/rsa_public.pem .env

To generate a decrypted env.json file from a .env file:

env-tool decrypt[--decrypt] ./.env ./.keys/rsa_private.pem env.json

To generate RSA public and private keys:

env-tool keygen[--keygen] .keys

The RSA public and private keys can be generated using the following OpenSSL commands:

openssl genpkey -algorithm RSA -out rsa_private.pem -pkeyopt rsa_keygen_bits:2048

openssl rsa -in rsa_private.pem -pubout -out rsa_public.pem

To generate the env-tool binary, run the following command:

npm run build

This will generate the binary in the builds folder. The binary can be used without a Node.js runtime.

The RSA public and private keys can be generated using the following OpenSSL commands:

It is important to store the private key in a secure location and keep it private. The private key is required to decrypt the environment variables stored in the .env file.
