# Certificado de cliente

La autenticación por certificado de cliente garantiza que las máquinas cliente dispongan de un certificado concreto al conectarse a PowerShell Universal. La comprobación del certificado se realiza durante la negociación HTTP, por lo que afecta a todo el servidor web y no puede configurarse por ruta.

Para obtener información detallada sobre la autenticación por certificado de cliente en ASP.NET Core 5.0, puede consultar la [documentación de Microsoft aquí](https://docs.microsoft.com/en-us/aspnet/core/security/authentication/certauth?view=aspnetcore-5.0).

## Habilitar la autenticación por certificado de cliente

Deberá habilitar el alojamiento HTTPS y activar la autenticación por certificado de cliente. En primer lugar, asegúrese de tener seleccionado un certificado HTTP y de haber establecido `ClientCertificateMode` en `RequireCertificate`. Estas opciones se pueden definir en el fichero appsettings.json.

```json
"Kestrel": {
  "Endpoints": {
    "HTTPS": {
      "Url": "https://*:5000",
      "ClientCertificateMode": "RequireCertificate",
      "Certificate": {
        "Subject": "localhost",
        "Store": "My",
        "Location": "LocalMachine",
        "AllowInvalid": "true"
      }
    }
  },
  "RedirectToHttps": "false"
},
```

A continuación, deberá habilitar la autenticación por certificado de cliente.

```json
"ClientCertificate": {
  "Enabled": "true"
},
```

## Autorización

Puede utilizar el fichero roles.ps1 para evaluar el certificado proporcionado por el cliente. Esto puede servir para determinar qué roles recibirá el usuario al conectarse a PSU.

Para evaluar las propiedades disponibles durante la autorización, puede serializar la variable `$user` que se proporciona a las funciones de política de roles.

```powershell
param($User)

$User | ConvertTo-Json | Out-File .\user.txt

$true
```

Recibirá información sobre el certificado dentro del objeto de usuario, similar a la siguiente.

```json
{
  "Claims": [
    {
      "Type": "issuer",
      "Value": "CN=Cert1, OU=Cert2, O=Org, L=Scottsdale, S=Arizona, C=US",
      "ValueType": "http://www.w3.org/2001/XMLSchema#string",
      "Issuer": "LOCAL AUTHORITY",
      "Properties": "System.Collections.Generic.Dictionary`2[System.String,System.String]"
    },
    {
      "Type": "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/thumbprint",
      "Value": "8D2212B6EA170A33055A5",
      "ValueType": "http://www.w3.org/2001/XMLSchema#base64Binary",
      "Issuer": "LOCAL AUTHORITY",
      "Properties": "System.Collections.Generic.Dictionary`2[System.String,System.String]"
    },
    {
      "Type": "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/x500distinguishedname",
      "Value": "CN=*.cert.com, OU=Domain Control Validated",
      "ValueType": "http://www.w3.org/2001/XMLSchema#string",
      "Issuer": "LOCAL AUTHORITY",
      "Properties": "System.Collections.Generic.Dictionary`2[System.String,System.String]"
    },
    {
      "Type": "http://schemas.microsoft.com/ws/2008/06/identity/claims/serialnumber",
      "Value": "009D21369",
      "ValueType": "http://www.w3.org/2001/XMLSchema#string",
      "Issuer": "LOCAL AUTHORITY",
      "Properties": "System.Collections.Generic.Dictionary`2[System.String,System.String]"
    },
    {
      "Type": "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/dns",
      "Value": "*.cert.com",
      "ValueType": "http://www.w3.org/2001/XMLSchema#string",
      "Issuer": "LOCAL AUTHORITY",
      "Properties": "System.Collections.Generic.Dictionary`2[System.String,System.String]"
    },
    {
      "Type": "http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name",
      "Value": "*.cert.com",
      "ValueType": "http://www.w3.org/2001/XMLSchema#string",
      "Issuer": "LOCAL AUTHORITY",
      "Properties": "System.Collections.Generic.Dictionary`2[System.String,System.String]"
    }
  ],
  "Identity": {
    "Name": "*.cert.com"
  }
}

```

Puede evaluar los claims mediante el método `HasClaim`. A continuación se muestra un ejemplo de comprobación de la huella digital del certificado.

```powershell
param($User)

$User.HasClaim('http://schemas.xmlsoap.org/ws/2005/05/identity/claims/thumbprint', '8D2212B6EA170A33055A5')
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.devolutions.net/powershell-universal/es/seguridad/enterprise-security/client-certificate.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
