dotenvx-plaintext-sync

CLI tool for syncing encrypted .env files across teams using dotenvx.

Why dotenvx-plaintext-sync?

dotenvx is a great tool for encrypting .env files. It's designed to run apps with encrypted env files directly (dotenvx run), but sometimes you need plaintext .env files:

• Your framework reads .env directly
• You want to keep existing workflows
• You need to inspect values during debugging

The problem with plaintext workflows

When decrypting .env files manually, operational risks emerge:

• Path mistakes - Typing paths manually every time leads to errors
• OS differences - Path separators and behaviors vary across systems
• Multi-environment chaos - Managing dev/staging/production separately is tedious
• Accidental commits - Easy to forget gitignore and leak secrets

How dotenvx-plaintext-sync helps

Problem	Solution
Path mistakes	Config file manages all paths centrally
OS differences	Consistent interface across platforms
Multi-environment	Just specify env name: dxps encrypt development
Accidental commits	Auto-configures gitignore, validates env paths are protected
Overwriting team values	Append-only encryption preserves existing keys
Losing local changes	Non-destructive decrypt outputs to latest/, not your working file
Over-sharing keys	Separate key files per environment

Prerequisites

• Python 3.11+
• dotenvx:

# npm
npm install -g @dotenvx/dotenvx

# brew
brew install dotenvx/brew/dotenvx

# curl
curl -sfS https://dotenvx.sh | sh

Installation

pip install dotenvx-plaintext-sync

Quick Start

# 1. Initialize in your project
cd your-project
dxps init

# 2. Create your plaintext env file
echo "API_KEY=secret123" > envs/.env.development

# 3. Encrypt it
dxps encrypt development
# → Creates enc/.env.development.enc and envs/keys/development.keys

# 4. Share envs/keys/development.keys with your team securely

# 5. Commit the encrypted file
git add enc/.env.development.enc
git commit -m "Add encrypted development env"

Directory Structure

After dxps init:

your-project/
├── dxps.json               # Configuration
├── enc/                    # Encrypted files (commit these)
│   └── .env.development.enc
├── envs/                   # Local files (gitignored)
│   ├── .env.development    # Plaintext source
│   ├── .env.staging
│   ├── .env.production
│   ├── keys/               # Key files
│   │   └── development.keys
│   └── latest/             # Decrypted output
│       └── .env.development
└── .gitignore              # Updated automatically

Usage

Encrypt

Add or update keys in your plaintext file, then encrypt:

dxps encrypt development

• First run: generates key file and .enc
• Subsequent runs: adds new keys to existing .enc (doesn't overwrite existing values)

Update existing values

To update values that already exist in the encrypted file:

dxps encrypt development --update

This will:

1. Compare your plaintext file with the encrypted file
2. Show a diff of changes (new keys and updated values)
3. Ask for confirmation before applying

=== Changes to be applied ===

[NEW]
  + NEW_API_KEY

[UPDATE]
  ~ DATABASE_URL
  ~ SECRET_KEY

Apply these changes? [y/N]:

Decrypt

Decrypt to latest/ directory (safe, doesn't overwrite your working file):

dxps decrypt development
# → Output: envs/latest/.env.development

Pull

Decrypt and apply directly to your working file in one step:

dxps pull development
# → Decrypts and copies to envs/.env.development

Configuration

Edit dxps.json:

{
  "env_dir": "envs",
  "envs": {
    "development": "envs/.env.development",
    "staging": "envs/.env.staging",
    "production": "envs/.env.production"
  },
  "enc_dir": "enc",
  "work_dir": "tmp/dxps"
}

Or use pyproject.toml:

[tool.dxps]
env_dir = "envs"
enc_dir = "enc"

[tool.dxps.envs]
development = "envs/.env.development"
staging = "envs/.env.staging"
production = "envs/.env.production"

Custom paths example

{
  "env_dir": "config/env",
  "envs": {
    "dev": "config/env/.env.dev",
    "prod": "config/env/.env.prod"
  }
}

Note: All env paths must be under env_dir. This is enforced to ensure gitignore protection.

Design Principles

• Safe by default - encrypt only adds new keys, use --update to modify existing values
• Non-destructive - decrypt outputs to latest/, use pull to apply to working file
• Validated - Checks that all values are encrypted, env paths are protected
• Confirmed - Updates require explicit y/N confirmation
