# Certificato autofirmato non valido in Chrome ed Edge

I certificati autofirmati predefiniti generati in Windows Server (precedenti al 2022) non sono più considerati validi da Chrome ed Edge. Per maggiori informazioni su Chrome, consulti la documentazione di Google sul [criterio RSAKeyUsageForLocalAnchorsEnabled](https://chromeenterprise.google/policies/#RSAKeyUsageForLocalAnchorsEnabled).

### Soluzione

In Windows Server 2022, è possibile generare un nuovo certificato autofirmato. Nelle versioni precedenti, è possibile utilizzare il seguente script PowerShell per generare un certificato autofirmato valido:

```powershell
#Create the cert and place it in the personal cert store
$cert = New-SelfSignedCertificate -DnsName $(([System.Net.Dns]::GetHostByName($env:computerName)).HostName) -CertStoreLocation "cert:\LocalMachine\My" -KeyUsage DigitalSignature,CertSign,CRLSign -KeyAlgorithm RSA -KeyLength 2048 -Provider "Microsoft Enhanced RSA and AES Cryptographic Provider" -NotAfter (Get-Date).AddYears(5)
```

## 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/server/it/knowledge-base/troubleshooting-articles/invalid-self-signed-certificate-in-chrome-and-edge.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.
