# FIPS (kryptering)

Løs fejlen med FIPS-validerede kryptografiske algoritmer i Remote Desktop Manager ved at justere den lokale sikkerhedspolitik eller filen exe.config.

`System.invalidoperationexception: this implementation is not part of the windows platform FIPS validated cryptographic algorithms.`

Problemet kan hænge sammen med, at FIPS-tilstanden er aktiveret.

Remote Desktop Manager bruger krypteringsalgoritmen AES/Rijndael og hashingalgoritmen SHA-256, som er implementeret af Microsoft .NET Framework. Hvis den lokale sikkerhedspolitik på Deres system gennemtvinger FIPS-kompatible implementeringer, kan Remote Desktop Manager ikke køre. De får derfor denne fejlmeddelelse.

### Løsning 1

For at rette denne fejl skal De konfigurere den lokale sikkerhedspolitik på Deres system, så den tillader algoritmeimplementeringer, der ikke er FIPS-kompatible.

Her er trinnene:

1. Gå til ***Kontrolpanel – Administrative værktøjer – Lokal sikkerhedspolitik – Åbn lokale politikker – Sikkerhedsindstillinger***.
2. Deaktivér valgmuligheden ***Systemkryptografi: Brug FIPS-kompatible algoritmer til kryptering, hashing og signering***.

Noget software (dvs. Cisco VPN Anyconnect) kræver brug af FIPS. Hvis det er Deres tilfælde, skal De implementere den alternative løsning, der er beskrevet nedenfor.

### Løsning 2

I installationsmappen for Remote Desktop Manager skal De oprette en tekstfil med navnet **RemoteDesktopManager.exe.config** med følgende indhold:

```
<configuration>
    <runtime>
        <enforceFIPSPolicy enabled="false"/>
    </runtime>
</configuration>
```

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.devolutions.net/rdm/da/knowledge-base/troubleshooting-articles/forticlient/fips-encryption.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
