     # ### Customer-supplied encryption keys
     #
     # By default, Google Cloud Storage manages server-side encryption keys on
     # your behalf. However, a [customer-supplied encryption
     # key](https://cloud.google.com/storage/docs/encryption#customer-supplied)
-    # can be provided with the `encryption_key` and `encryption_key_sha256`
-    # options. If given, the same key and SHA256 hash also must be provided to
-    # subsequently download or copy the file. If you use customer-supplied
-    # encryption keys, you must securely manage your keys and ensure that they
-    # are not lost. Also, please note that file metadata is not encrypted, with
-    # the exception of the CRC32C checksum and MD5 hash. The names of files and
-    # buckets are also not encrypted, and you can read or update the metadata of
-    # an encrypted file without providing the encryption key.
