Encryption and Decryption Principles Large-size data encryption Figure 1 Encrypting a local file The process is as follows: Create a CMK on KMS. Call the create-datakey API of KMS to create a DEK. Then you get a plaintext DEK and a ciphertext DEK.
For details, see Encrypting an Image in the Image Management Service User Guide. The encryption attribute of an existing disk cannot be changed. You can create new disks and determine whether to encrypt the disks or not.
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.
For details about the example code, see ISV Server Encrypting the Username and Password After Resource Enabling. memo No String 1,024 Remarks. The following table describes the UsageInfo data structure.
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.

Encrypting AK/SK for Deploying an APM Agent in a CCE Container Encrypt the AK/SK when deploying an APM Agent on CCE. Suggestions on APM Security Configuration This document provides guidance for enhancing the overall security of APM.
With the agency, SFS can obtain KMS keys for encrypting or decrypting file systems. You can view the agency in the agency list on the IAM console. Creating a Cloud Service Agency on the IAM Console Log in to the IAM console.
Some performance overhead may be added, especially when it is used for encrypting and decrypting large amounts of data. It applies to environments that require high data transmission security, such as finance and healthcare industries.
parameter Explanation: Key for encrypting the object when SSE-C is used Restrictions: The value is a Base64-encoded 256-bit key, for example, K7QkYpBkM5+hca27fsNkUnNVaobncnLht/rCB2o/9Cw=.

AK/SK-based authentication: Requests are authenticated by encrypting the request body using an AK/SK pair. AK/SK-based authentication is recommended because it is more secure than token-based authentication. Token The validity period of a token is 24 hours.
Some performance overhead may be added, especially when it is used for encrypting and decrypting large amounts of data. It applies to environments that require high data transmission security, such as finance and healthcare industries.
After user 1 grants permissions, the system automatically creates key evs/default for encrypting EVS disks. When user 1 uses the encryption feature for the first time, the user must grant the KMS access permissions to EVS.
Example of Encryption Encrypting an Object to Be Uploaded Sample code: SSE-C encryption static OBSClient *client; NSString *endPoint = @"your-endpoint"; // Hard-coded or plaintext AK/SK are risky.
Example of Encryption Encrypting an Object to Be Uploaded Sample code: SSE-C encryption static OBSClient *client; NSString *endPoint = @"your-endpoint"; // Hard-coded or plaintext AK/SK are risky.
Encrypting an Object to Be Uploaded Sample code: // Hard-coded or plaintext AK/SK are risky. For security purposes, encrypt your AK/SK and store them in the configuration file or environment variables.
Envelope Encryption Envelope encryption is the practice of encrypting data with a DEK and then encrypting the DEK with a root key that you can fully manage. In this case, CMKs are not required for encryption or decryption. DEK A data encryption key (DEK) is used to encrypt data.
