# Generating bcrypt-hashed password

With version 14 of wg-easy, a password hashed with bcrypt is needed instead of the plain-text password string. This doc explains how to generate the hash based on a plain-text password.

## Using Docker + node

- You are using docker compose

    The easiest way to generate a bcrypt password hash with wgpw is using docker and node:

    ```sh
    docker run ghcr.io/wg-easy/wg-easy:14 node -e 'const bcrypt = require("bcryptjs"); const hash = bcrypt.hashSync("YOUR_PASSWORD", 10); console.log(hash.replace(/\$/g, "$$$$"));'
    ```

    The hashed password will get printed on your terminal. Copy it and use on the `PASSWORD_HASH` environment variable in your docker compose.

- You are using `docker run`

    If you are using `docker run` for running wg-easy, you must enclose the hash string in single quotes (`'...'`). You can use this command:

    ```sh
    docker run --rm ghcr.io/wg-easy/wg-easy:14 node -e "const bcrypt = require('bcryptjs'); const hash = bcrypt.hashSync('YOUR_PASSWORD', 10); console.log('\'' + hash + '\'');"
    ```

    The hashed password will get printed on your terminal. Copy it and use on the `PASSWORD_HASH` environment variable in your docker run command.

## Using Docker + wgpw

`wg-password` (wgpw) is a script that generates bcrypt password hashes. You can use it with docker:

```sh
docker run ghcr.io/wg-easy/wg-easy:14 wgpw YOUR_PASSWORD
```

You will see an output similar to this:

```sh
PASSWORD_HASH='$2b$12$coPqCsPtcFO.Ab99xylBNOW4.Iu7OOA2/ZIboHN6/oyxca3MWo7fW'
```

In this example, the `$2b$12$coPqCsPtcFO.Ab99xylBNOW4.Iu7OOA2/ZIboHN6/oyxca3MWo7fW` string is your hashed password. For using it with docker-compose, you need to escape each `$` characters by adding another `$` before them, or they will get interpreted as variables. The final password you can use in docker-compose will look like this:

```sh
$$2b$$12$$coPqCsPtcFO.Ab99xylBNOW4.Iu7OOA2/ZIboHN6/oyxca3MWo7fW
```
