Dotenv Mask Editor

A visual editor for environment files with automatic secret masking.

Dotenv Mask Editor provides a table-based interface for .env files. It is designed to reduce the accidental exposure of sensitive values by masking strings that meet a length threshold. All processing is done locally within your editor.

Features

• Custom Editor: Provides a grid view for .env, .env.*, and *.env files.
• Masking: Values with 6 or more characters are replaced with ****** in the display.
• Editing: Supports direct modification of both keys and values.
• Privacy: Masked values are only revealed during active editing.
• Local execution: The extension has no external dependencies and does not make network requests.

Usage

1. Open a .env file. The extension should associate automatically.
2. Click a cell to edit its content. Masked values will reveal their raw text while the cell is focused.
3. Move focus away from the cell to save changes and re-apply masking.

If the file opens in the standard text editor, right-click the file tab and select "Reopen Editor With..." followed by "Dotenv Mask Editor".

Configuration

Custom file patterns can be added via VS Code settings:

{
  "envSecretMasking.filePatterns": [
    "*.config"
  ]
}

Installation

Available through the VS Code Marketplace. Search for "Dotenv Mask Editor".
