# Environment variables

A full list of available environment variables that allow override
internal features.

#### VERDACCIO_LEGACY_ALGORITHM

Allows to define the specific algorithm for the token signature which by default is `aes-256-ctr`. The algorithm must be supported by `crypto.createCipheriv` and `crypto.createDecipheriv`.

#### VERDACCIO_LEGACY_ENCRYPTION_KEY

By default, the token stores in the database, but using this variable allows to get it from memory, the length must be 32 characters otherwise will throw an error.

#### VERDACCIO_PUBLIC_URL

Define a specific public url for your server, it overrules the `Host` and `X-Forwarded-Proto` header if a reverse proxy is being used, it takes in account the `url_prefix` if is defined.

This is handy in such situations where a dynamic url is required.

eg:

```
VERDACCIO_PUBLIC_URL='https://somedomain.org';
url_prefix: '/my_prefix'

// url -> https://somedomain.org/my_prefix/

VERDACCIO_PUBLIC_URL='https://somedomain.org';
url_prefix: '/'

// url -> https://somedomain.org/

VERDACCIO_PUBLIC_URL='https://somedomain.org/first_prefix';
url_prefix: '/second_prefix'

// url -> https://somedomain.org/second_prefix/'
```

#### VERDACCIO_FORWARDED_PROTO

The default header to identify the protocol is `X-Forwarded-Proto`, but there are some environments which [uses something different](https://github.com/verdaccio/verdaccio/issues/990), to change it use the variable `VERDACCIO_FORWARDED_PROTO`

```
$ VERDACCIO_FORWARDED_PROTO=CloudFront-Forwarded-Proto verdaccio --listen 5000
```

#### VERDACCIO_STORAGE_PATH

By default, the storage is taken from config file, but using this variable allows to set it from environment variable.

#### VERDACCIO_STORAGE_NAME

The database name for `@verdaccio/local-storage` is by default `.verdaccio-db.json`, but this can be update by using this variable.
