Interfaces Related to Server-Side Encryption

This section lists the interfaces related to server-side encryption and describes transfer protocols and authentication applicable to the interfaces.

The following tables describe transfer protocols and authentication applicable to the interfaces related to server-side encryption.

Table 1 Transfer protocols and authentication applicable to SSE-C-related interfaces

Interface	Transfer Protocol	Authentication
PUT Object	HTTPS	V2 or V4
POST Object	HTTPS	V2 or V4
Initiate Multipart Upload	HTTPS	V2 or V4
HEAD Object	HTTPS	V2 or V4
GET Object	HTTPS	V2 or V4
Upload Part	HTTPS	V2 or V4
Complete Multipart Upload	HTTP or HTTPS	V2 or V4

Table 2 Transfer protocols and authentication applicable to SSE-KMS-related interfaces

Interface	Transfer Protocol	Authentication
PUT Object	HTTPS	V4
POST Object	HTTPS	V4
Initiate Multipart Upload	HTTPS	V4
HEAD Object	HTTP or HTTPS	V2 or V4
GET Object	HTTPS	V4
Upload Part	HTTPS	V4
Complete Multipart Upload	HTTP or HTTPS	V2 or V4

Table 3 Transfer protocols and authentication applicable to PUT Object - Copy interfaces

Source Object	Target Object	Transfer Protocol	Authentication
Non-encrypted object	Object encrypted using SSE-KMS	HTTPS	V4
Object encrypted using SSE-KMS	Object encrypted using SSE-KMS	HTTPS	V4
Object encrypted using SSE-C	Object encrypted using SSE-KMS	HTTPS	V4
Non-encrypted object	Object encrypted using SSE-C	HTTPS	V2 or V4
Object encrypted using SSE-KMS	Object encrypted using SSE-C	HTTPS	V2 or V4
Object encrypted using SSE-C	Object encrypted using SSE-C	HTTPS	V2 or V4

Object encrypted using SSE-KMS	Non-encrypted object	HTTP or HTTPS	V2 or V4
Object encrypted using SSE-C	Non-encrypted object	HTTP or HTTPS	V2 or V4

Table 4 Transfer protocols and authentication applicable to Upload Part - Copy interfaces

Source Object	Target Part	Transfer Protocol	Authentication
Non-encrypted object	Part encrypted using SSE-KMS	HTTP or HTTPS	V2 or V4
Object encrypted using SSE-KMS	Part encrypted using SSE-KMS	HTTP or HTTPS	V2 or V4

Object encrypted using SSE-KMS	Part encrypted using SSE-C	HTTPS	V2 or V4
Object encrypted using SSE-C	Part encrypted using SSE-C	HTTPS	V2 or V4
Non-encrypted object	Non-encrypted part	HTTP or HTTPS	V2 or V4
Object encrypted using SSE-KMS	Non-encrypted part	HTTP or HTTPS	V2 or V4
Object encrypted using SSE-C	Non-encrypted part	HTTP or HTTPS	V2 or V4
