Properties

ChunkSize

public int? ChunkSize { get; set; }

The chunk size to use for each request.

Property Value
Type	Description
`Nullable<Int32>`

DownloadValidationMode

public DownloadValidationMode? DownloadValidationMode { get; set; }

Specifies whether or not the object's hash should be validated. If this property is null, the hash will always be validated.

Property Value
Type	Description
`Nullable<DownloadValidationMode>`

Remarks

This is effectively an escape hatch for situations where hash validation fails. See https://github.com/googleapis/google-cloud-dotnet/issues/1641 for background on this option. It is recommended that you leave this option unset (or use Automatic) unless you are knowingly downloading data for an object where hashing will fail.

The current implementation defaults to Always; in a future major version the default will change to Automatic which will automatically ignore the hash where validation is expected to fail (even with valid data).

EncryptionKey

public EncryptionKey EncryptionKey { get; set; }

The encryption key to use for this operation. If this property is null, the EncryptionKey will be used instead. Use None to remove encryption headers from this request.
