API Operations Related to Server-Side Encryption

This section lists the operations related to server-side encryption and describes HTTP protocols applicable to the operations.

The following table describes the requirements on the transmission protocols used by the API operation related to server-side encryption.

Table 1 Requirements for the transmission protocol used by the operations related to the SSE-C

Operation	Transfer Protocol
PutObject	HTTPS
PostObject	HTTPS
InitiateMultipartUpload	HTTPS
HeadObject	HTTPS
GetObject	HTTPS
UploadPart	HTTPS
CompleteMultipartUpload	HTTP or HTTPS

Table 2 Requirements for the transfer protocol used by the operations related to the SSE-KMS

Operation	Transfer Protocol
PutObject	HTTPS
PostObject	HTTPS
InitiateMultipartUpload	HTTPS
HeadObject	HTTP or HTTPS
GetObject	HTTPS
UploadPart	HTTPS
CompleteMultipartUpload	HTTP or HTTPS

Table 3 Requirements for transfer protocol used by the CopyObject operation

Source Object	Target Object	Transfer Protocol
Non-encrypted object	Object encrypted using SSE-KMS	HTTPS
Object encrypted using SSE-KMS	Object encrypted using SSE-KMS	HTTPS
Object encrypted using SSE-C	Object encrypted using SSE-KMS	HTTPS
Non-encrypted object	Object encrypted using SSE-C	HTTPS
Object encrypted using SSE-KMS	Object encrypted using SSE-C	HTTPS
Object encrypted using SSE-C	Object encrypted using SSE-C	HTTPS
Non-encrypted object	Non-encrypted object	HTTP or HTTPS
Object encrypted using SSE-KMS	Non-encrypted object	HTTP or HTTPS
Object encrypted using SSE-C	Non-encrypted object	HTTP or HTTPS

Table 4 Requirements for the transfer protocol used by the UploadPart-Copy operation

Source Object	Target Part	Transfer Protocol
Non-encrypted object	Part encrypted using SSE-KMS	HTTP or HTTPS
Object encrypted using SSE-KMS	Part encrypted using SSE-KMS	HTTP or HTTPS
Object encrypted using SSE-C	Part encrypted using SSE-KMS	HTTP or HTTPS
Non-encrypted object	Part encrypted using SSE-C	HTTPS
Object encrypted using SSE-KMS	Part encrypted using SSE-C	HTTPS
Object encrypted using SSE-C	Part encrypted using SSE-C	HTTPS
Non-encrypted object	Non-encrypted part	HTTP or HTTPS
Object encrypted using SSE-KMS	Non-encrypted part	HTTP or HTTPS
Object encrypted using SSE-C	Non-encrypted part	HTTP or HTTPS
