We are excited to announce our new API Documentation.
Optional
BucketOptional
ChecksumCRC32The base64-encoded, 32-bit CRC32 checksum of the object. This will only be present if it was uploaded with the object. With multipart uploads, this may not be a checksum value of the object. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.
Optional
ChecksumCRC32CThe base64-encoded, 32-bit CRC32C checksum of the object. This will only be present if it was uploaded with the object. With multipart uploads, this may not be a checksum value of the object. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.
Optional
ChecksumSHA1The base64-encoded, 160-bit SHA-1 digest of the object. This will only be present if it was uploaded with the object. With multipart uploads, this may not be a checksum value of the object. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.
Optional
ChecksumSHA256The base64-encoded, 256-bit SHA-256 digest of the object. This will only be present if it was uploaded with the object. With multipart uploads, this may not be a checksum value of the object. For more information about how checksums are calculated with multipart uploads, see Checking object integrity in the Amazon S3 User Guide.
Optional
ETagEntity tag for the uploaded object.
Optional
RequestIf present, indicates that the requester was successfully charged for the request.
Optional
SSECustomerIf server-side encryption with a customer-provided encryption key was requested, the response will include this header confirming the encryption algorithm used.
Optional
SSECustomerIf server-side encryption with a customer-provided encryption key was requested, the response will include this header to provide round-trip message integrity verification of the customer-provided encryption key.
Optional
SSEKMSKeyIf present, specifies the ID of the Key Management Service (KMS) symmetric encryption customer managed key was used for the object.
Optional
ServerThe server-side encryption algorithm used when storing this object in Amazon S3 (for example,
AES256
, aws:kms
).
Indicates whether the multipart upload uses an S3 Bucket Key for server-side encryption with Key Management Service (KMS) keys (SSE-KMS).
