The Base64 encoded, 32-bit CRC32C checksum of the object. This checksum is only present if the checksum was uploaded with the object. For more information, see Checking object integrity in the Amazon S3 User Guide.

The Base64 encoded, 64-bit CRC64NVME checksum of the object.

For more information, see Checking object integrity in the Amazon S3 User Guide.

The Base64 encoded, 160-bit SHA1 digest of the object. This checksum is only present if the checksum was uploaded with the object. For more information, see Checking object integrity in the Amazon S3 User Guide.
