TypeError: 'hashlib.HASH' object is not callable in validate_data method

[AissaGeek]

There is a bug in the validate_data method of the DownloadWorker class in downloader/__init__.py. The hash_function is being used incorrectly as a callable, which results in a TypeError. The hash_function is an instance and should use its update method instead.

Suggested fix

hash_function.update(data)
hash_value = base64.b64encode(hash_function.digest()).decode()
