## What is the Vault

A good amount of the tools you'll be using in Flowsint require third party API keys.

The **Vault** (*"Coffre fort"* in french) is the place to centralize and securely store those API keys. 
Weither you have a local instance of Flowsint or one fully deployed on a distributed system, you need to have your keys securely stored.

## Adding a key

In the Flowsint enricher ecosystem, the API keys follow a specific format, being in uppercase letters, and with a declarative name that follows `<service>_API_KEY`.

## Current limitations

For now, we cannot match a particular key from the Vault to an enricher **directly from the UI**. The enricher declares the API key variable name it requires, like the following in the core of the Enricher:

```python
@classmethod
    def get_params_schema(cls) -> List[Dict[str, Any]]:
        """Declare required parameters for this enricher"""
        return [
            {
                "name": "PDCP_API_KEY",
                "type": "vaultSecret",
                "description": "The ProjectDiscovery Cloud Platform API key for asnmap.",
                "required": True,
            },
        ]
```

This is a known limitation and we are working on improving this. 

In the meanwhile, here is a list of the needed keys to run Flowsint at it's full potential:

```bash
# for enrichers
WHOXY_API_KEY # Whoxy domain search engine [WHOXY]
PDCP_API_KEY # ProjectDiscovery Cloud Platform [ASNMAP], [NAABU] etc
HIBP_API_KEY # HaveIBeenPwned API key [HIBP]
ETHERSCAN_API_KEY # Etherscan crypto API key [ETHERSCAN]
# for Flo, AI assistant
MISTRAL_API_KEY
# but other providers will be supported soon (ChatGPT, etc.)
```

There are also some other tools that could need a bunch of other API keys like [Subfinder](https://github.com/projectdiscovery/subfinder). Configuring them is not possible for now, but will be soon.

Stay tuned for updates as those mechanisms may vary in the future, as the goal is to keep the user experience as smooth as possible.
