Alibaba Cloud KMS Go SDK

Alibaba Cloud KMS Go SDK can help Golang developers to use the KMS.

Advantage

Alibaba Cloud KMS SDK helps Java developers quickly use all APIs of Alibaba Cloud KMS products:

  • KMS resource management and key operations can be performed through KMS public gateway access
  • You can perform key operations through KMS instance gateway

Requirements

  • Golang 1.13 or later.

Installation

If you use go mod to manage your dependence, You can declare the dependency on AlibabaCloud KMS Go SDK in the go.mod file:

require (
	github.com/aliyun/alibabacloud-kms-go-sdk v1.2.4
)

Or, Run the following command to get the remote code package:

$ go get -u github.com/aliyun/alibabacloud-kms-go-sdk

Introduction to KMS Client

KMS client struct Introduction Usage scenarios
Client KMS resource management and key operations for KMS instance gateways are supported 1. Scenarios where key operations are performed only through VPC gateways.
2. KMS resource management scenarios that only use public gateways.
3. Scenarios where you want to perform key operations through VPC gateways and manage KMS resources through public gateways.
TransferClient Users can migrate from KMS 1.0 key operations to KMS 3.0 key operations Users who use Alibaba Cloud SDK to access KMS 1.0 key operations need to migrate to KMS 3.0

Sample code

1. Scenarios where key operations are performed only through VPC gateways.
Refer to the following sample code to call the KMS AdvanceEncrypt API. For more API examples, see operation samples

KMS instance performance testing

If you need to use the KMS instance SDK for KMS instance performance testing, please refer to the sample code of the pressure measurement tools in the directory named benchmarks , compile it into an executable program and run it with the following command:

nohup ./benchmark -case=encrypt -client_key_file=./ClientKey_****.json -client_key_password=**** -endpoint=kst-****.cryptoservice.kms.aliyuncs.com -key_id=key-**** -data_size=32 -concurrence_nums=32 -duration=600 -log_path=./log > aes_256_enc.out 2>&1&

How to compile and use the stress test tool, please refer to the document.
