# Detailed description
As a Developer,
I want to be able to simulate BadDigest and InvalidDigest errors,
So that I can test the error handling logic

## Expected behavior
https://docs.aws.amazon.com/AmazonS3/latest/API/ErrorResponses.html
BadDigest: The Content-MD5 you specified did not match what we received.
InvalidDigest: The Content-MD5 you specified is not valid.

## Actual behavior
localstack returns InvalidDigest when MD5 does not match payload.


bucket_name = 'test-bucket-%s' % short_uid()
        self.s3_client.create_bucket(Bucket=bucket_name)
        self.s3_client.put_object(Bucket=bucket_name, Key='error.html', Body='This is the error document')
        self.s3_client.put_bucket_website(
            Bucket=bucket_name,
            WebsiteConfiguration={'ErrorDocument': {'Key': 'error.html'}}
        )
        url = self.s3_client.generate_presigned_url(
            'get_object', Params={'Bucket': bucket_name, 'Key': 'nonexistent'}
        )
        response = requests.get(url, verify=False)
