Does Google Cloud Storage client in Python check CRC (or MD5) automatically?

I have tried to find out if GCS Python client, and more specifically, blob.upload_from_file() and blob.download_to_file() check integrity of the uploaded or downloaded file automatically. If not, how can I check the CRC hash programmatically? Any pointers to documentation or source code would be appreciated.

  • Edit(06/29/22) Checksums in Python are now available for md5 and crc32c for uploads and downloads.

    For example: Blob.download_as_bytes() has a new parameter named checksum with three values (None, 'md5', 'crc32c') https://googleapis.dev/python/storage/latest/blobs.html#google.cloud.storage.blob.Blob.download_as_bytes
