The cloud Key Management System (KMS) is a service where the cloud manages encrypted keys on behalf of users (Google Cloud Platform (GCP) KMS, Amazon Web Services (AWS) KMS).

Blockchain Open API – KMS API allows you to use keys stored in cloud KMS as your blockchain account wallet keys (private Key, or wallet private key). With the KMS API, users can generate transactions, sign them, and send them to the blockchain without directly managing their blockchain account wallet keys, via the keys stored in KMS instead. The cloud KMS platforms supported by the KMS API are GCP and AWS.

For example, the KMS API can be used as follows:

If you already have a key in cloud KMS

Prepare cloud credentials
Register cloud service account information (Credentials) at Hive Console > Blockchain > KMS Credentials > Add Credentials and obtain x-credential-id
Prepare cloud KMS key information
Call an API to register wallet address
Acquire wallet address
Query KMS wallet information
Create transactions with KMS wallet: Call APIs for generating new transactions such as sending tokens and deploying smart contracts
Sign the created transaction with KMS Sign API
Send the signed transaction to the blockchain network

If you are not using cloud KMS, or if there are no keys in cloud KMS

Prepare the cloud KMS service account
Create wallet key: Generated it by the wallet key creation API
1. Prepare cloud credentials
2. Prepare Blockchain API authentication key
3. Register cloud service account information (Credentials) at Hive Console > Blockchain > KMS Credentials > Add Credentials and obtain x-credential-id
4. Use x-credential-id and the API authentication key to create KMS wallet key
5. Acquire wallet key and wallet address
Query KMS wallet information
Create transactions with KMS wallet: Call APIs for generating new transactions such as sending tokens and deploying smart contracts
Sign the created transaction with KMS Sign API
Send the signed transaction to the blockchain network

Pre-requisites

Creating Blockchain Account Wallet Address and KMS Wallet Key

Creates a wallet key in KMS using your cloud service account, and based on this wallet key, creates a blockchain account wallet address. The wallet key is stored in KMS and cannot be verified. If there is a delay during key creation process, the wallet address might not be included in the API response. You can retrieve the wallet address using the KMS Wallet Information Inquiry API with the key ID (keyId).
