# VerifyFileHash task

Verifies that a file matches the expected file hash.
Verifies that a file matches the expected file hash. If the hash doesn't match, the task fails.

This task was added in 15.8, but requires a [workaround](https://github.com/Microsoft/msbuild/pull/3999#issuecomment-458193272) to use for MSBuild versions below 16.0.

```

On MSBuild 16.5 and later, if you don't want the build to fail when the hash doesn't match, such as if you are using the hash comparison as a condition for control flow, you can downgrade the warning to a message using the following code:

```xml
<PropertyGroup>
<MSBuildWarningsAsMessages>$(MSBuildWarningsAsMessages);MSB3952</MSBuildWarningsAsMessages>
</PropertyGroup>

<Target Name="DemoVerifyCheck">
<VerifyFileHash File="$(MSBuildThisFileFullPath)"
Hash="1"
ContinueOnError="WarnAndContinue" />

<PropertyGroup>
<HashMatched>$(MSBuildLastTaskResult)</HashMatched>
</PropertyGroup>

<Message Condition=" '$(HashMatched)' != 'true'"
Text="The hash didn't match" />

<Message Condition=" '$(HashMatched)' == 'true'"
Text="The hash did match" />
</Target>
```
