# ITrustArbitrator

**Namespace:** `Lacuna.Pki`  
**Assembly:** `Lacuna.Pki`  
_Interface_

```csharp
public interface ITrustArbitrator
```

## Métodos

### `GetCertificateStore()`

Returns a certificate store based on the arbitrator root certificates

```csharp
ICertificateStore GetCertificateStore()
```

**Retorno**

[`ICertificateStore`](https://docs.lacunasoftware.com/api/Lacuna.Pki.Stores/ICertificateStore) — Certificate store based on the arbitrator root certificates. Can be null.

**Comentários**

If that method does not make sense for your implementation or there is
            no certificate in your arbitrator logic, it can return null.

### `IsRootTrusted(PKCertificate, DateTimeOffset?, out ValidationResults)`

Determines whether a given PKCertificate is trusted, optionally outputting a ValidationResults object
that represents validations done while asserting the trust status.

```csharp
bool IsRootTrusted(PKCertificate root, DateTimeOffset? dateReference, out ValidationResults vr)
```

**Parâmetros**

| Nome | Tipo | Descrição |
|---|---|---|
| `root` | [`PKCertificate`](https://docs.lacunasoftware.com/api/Lacuna.Pki/PKCertificate) | The certificate for which the trust status must be determined. |
| `dateReference` | [`DateTimeOffset?`](https://learn.microsoft.com/dotnet/api/system.datetimeoffset) | An optional date reference on which the trust is to be asserted. If null, validation is done considering the present moment (now). |
| `vr` | [`ValidationResults`](https://docs.lacunasoftware.com/api/Lacuna.Pki/ValidationResults) | The retults of the validations necessary to assertain the trust status. Implementors of this interface should set this parameter to null             if no validations where required. |

**Retorno**

[`bool`](https://learn.microsoft.com/dotnet/api/system.boolean) — Whether the given certificate is to be trusted or not.
