Server-Side Encryption Overview

If you have any questions during development, post them on the Issues page of GitHub. For details about parameters and usage of each API, see the API Reference.

OBS provides server-side encryption for objects, so that they will be encrypted or decrypted when you upload them to or download them from a bucket.

The encryption and decryption happen on the server side.

There are different encryption methods for you to choose from.

When server-side encryption is used, the returned ETag value is not the object's MD5 value. OBS will verify the object's MD5 value as long as the upload request includes the Content-MD5 header, no matter whether server-side encryption is used or not.

When server-side encryption is used, you are advised to use HTTPS to transmit and receive data.

For more information, see Server-Side Encryption.
