What Techniques Can I Use to Encrypt Data on OBS?

Before uploading your data to OBS, you can encrypt the data to ensure security during transmission and storage. OBS has no restrictions on client encryption techniques.

OBS allows you to encrypt objects with server-side encryption so that the objects can be securely stored in OBS.

The objects to be uploaded can be encrypted using SSE-KMS. When using KMS for server-side encryption, you need to first create a key, or you can use the default key provided by KMS. OBS uses the key you provide to perform server-side encryption.

After server-side encryption is enabled, objects to be uploaded will be encrypted and stored on the server. When objects are downloaded, they will be decrypted on the server first and then returned in plaintext to you.

OBS supports SSE-KMS, SSE-OBS, and SSE-C when calling APIs. With SSE-C, OBS uses the customer-provided keys and their MD5 values for server-side encryption.
