## Construtores

### `AttributeCertificate(byte[], ICertificateStore)`

```csharp
protected AttributeCertificate(byte[] certContent, ICertificateStore certStore)
```

**Parâmetros**

| Nome | Tipo | Descrição |
|---|---|---|
| `certContent` | [`byte[]`](https://learn.microsoft.com/dotnet/api/system.byte) |  |
| `certStore` | [`ICertificateStore`](https://docs.lacunasoftware.com/api/Lacuna.Pki.Stores/ICertificateStore) |  |

## Propriedades

### `Attributes`

```csharp
public X509Attributes Attributes { get; protected set; }
```

**Retorno**

[`X509Attributes`](https://docs.lacunasoftware.com/api/Lacuna.Pki/X509Attributes)

### `HolderName`

```csharp
public GeneralNames HolderName { get; protected set; }
```

**Retorno**

[`GeneralNames`](https://docs.lacunasoftware.com/api/Lacuna.Pki/GeneralNames)

### `HolderPKCertificate`

```csharp
public AttributeCertificateBaseCertificateId HolderPKCertificate { get; protected set; }
```

**Retorno**

[`AttributeCertificateBaseCertificateId`](https://docs.lacunasoftware.com/api/Lacuna.Pki/AttributeCertificateBaseCertificateId)

---

### `IsSelfSigned`

Denotes whether this is a self-signed certificate (root certificate) or not.

NOTICE: never test the condition Issuer==null to assertain if a certificate is self-signed,
since that condition may throw an exception in case the certificate is not a self-signed certificate but its
issuer could not be located. For such purposes, use this property instead.
