Code Example: Encrypting (SSE-C) and Uploading an Object The following code shows an example of encrypting an object with SSE-C before uploading it: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 // Enter the endpoint corresponding to the bucket.
Table 1 Header fields used for encrypting objects in SSE-C mode Element Description x-obs-server-side-encryption-customer-algorithm Indicates the encryption algorithm for the object when SSE-C is used.

Encrypting an Object Method 1: Enable server-side encryption when you create a bucket. Then, all types of objects uploaded to the bucket will be automatically encrypted with the encryption method and key you specified during bucket creation.
SseKms string Explanation: SSE-KMS is used for encrypting objects on the server side. SseKmsKey string Explanation: ID of the KMS master key when SSE-KMS is used. SseC string Explanation: SSE-C is used for encrypting objects on the server side.
