上传对象加密

以下代码展示了在上传对象时使用服务端加密功能：

// 引入依赖包
import (
       "fmt"
       "obs"
)
 
var ak = "*** Provide your Access Key ***"
var sk = "*** Provide your Secret Key ***"
var endpoint = "https://your-endpoint"
 
// 创建ObsClient结构体
var obsClient, _ = obs.New(ak, sk, endpoint)
 
func main() {
       input := &obs.PutFileInput{}
       input.Bucket = "bucketname"
       input.Key = "objectkey"
       input.SourceFile = "localfile"
       // 设置SSE-C算法加密对象
       input.SseHeader = &obs.SseCHeader{Encryption: "AES256", Key: "your base64-encoded sse-c key generated by AES-256 algorithm"}
       output, err := obsClient.PutFile(input)
       if err == nil {
              fmt.Printf("RequestId:%s\n", output.RequestId)
       } else if obsError, ok := err.(obs.ObsError); ok {
              fmt.Printf("Code:%s\n", obsError.Code)
              fmt.Printf("Message:%s\n", obsError.Message)
       }
 
       input.Bucket = "bucketname"
       input.Key = "objectkey2"
       input.SourceFile = "localfile2"
       // 设置SSE-KMS算法加密对象
       input.SseHeader = &obs.SseKmsHeader{Encryption: "kms"}
       output, err = obsClient.PutFile(input)
       if err == nil {
              fmt.Printf("RequestId:%s\n", output.RequestId)
       } else if obsError, ok := err.(obs.ObsError); ok {
              fmt.Printf("Code:%s\n", obsError.Code)
              fmt.Printf("Message:%s\n", obsError.Message)
       }
}

下载对象解密

以下代码展示了在下载对象时使用服务端解密功能：

// 引入依赖包
import (
       "fmt"
       "obs"
)
 
var ak = "*** Provide your Access Key ***"
var sk = "*** Provide your Secret Key ***"
var endpoint = "https://your-endpoint"
 
// 创建ObsClient结构体
var obsClient, _ = obs.New(ak, sk, endpoint)
 
func main() {
       input := &obs.GetObjectInput{}
       input.Bucket = "bucketname"
       input.Key = "objectkey"
       //设置SSE-C算法解密对象，此处的密钥必须和上传对象加密时使用的密钥一致
       input.SseHeader = &obs.SseCHeader{Encryption: "AES256", Key: "your base64-encoded sse-c key generated by AES-256 algorithm"}
       output, err := obsClient.GetObject(input)
       if err == nil {
              defer output.Body.Close()
              fmt.Printf("ETag:%s\n", output.ETag)
       } else if obsError, ok := err.(obs.ObsError); ok {
              fmt.Printf("Code:%s\n", obsError.Code)
              fmt.Printf("Message:%s\n", obsError.Message)
       }
}
