Checksum - Amazon Simple Storage Service (original) (raw)

Contains all the possible checksum or digest values for an object.

Contents

ChecksumCRC32

The Base64 encoded, 32-bit CRC32 checksum of the object. This checksum is only be present if the checksum was uploaded with the object. When you use an API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.

Type: String

Required: No

ChecksumCRC32C

The Base64 encoded, 32-bit CRC32C checksum of the object. This checksum is only present if the checksum was uploaded with the object. When you use an API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.

Type: String

Required: No

ChecksumCRC64NVME

The Base64 encoded, 64-bit CRC64NVME checksum of the object. This checksum is present if the object was uploaded with the CRC64NVME checksum algorithm, or if the object was uploaded without a checksum (and Amazon S3 added the default checksum, CRC64NVME, to the uploaded object). For more information, see Checking object integrity in the Amazon S3 User Guide.

Type: String

Required: No

ChecksumSHA1

The Base64 encoded, 160-bit SHA1 digest of the object. This will only be present if the object was uploaded with the object. When you use the API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.

Type: String

Required: No

ChecksumSHA256

The Base64 encoded, 256-bit SHA256 digest of the object. This will only be present if the object was uploaded with the object. When you use an API operation on an object that was uploaded using multipart uploads, this value may not be a direct checksum value of the full object. Instead, it's a calculation based on the checksum values of each individual part. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.

Type: String

Required: No

ChecksumType

The checksum type that is used to calculate the object’s checksum value. For more information, see Checking object integrity in the Amazon S3 User Guide.

Type: String

Valid Values: COMPOSITE | FULL_OBJECT

Required: No
