Alibaba Cloud KMS Secret Management

This Skill provides core functionality for Alibaba Cloud Key Management Service (KMS) secret management, supporting CRUD operations on secrets.

Scenario Description

KMS Secret Management service is used to securely store, manage, and access sensitive information, such as:

Database connection credentials
API keys
OAuth tokens
Certificate private keys
Other sensitive data requiring secure storage

Architecture: Alibaba Cloud KMS Service + Secret Management (Secrets Manager)

Environment Setup

Dependency: Aliyun CLI. If
command not found
error occurs, refer to references/cli-installation-guide.md for installation.

Timeout Configuration

Set appropriate timeouts for CLI commands to avoid hanging:

bash

# Set timeout environment variables (in seconds)
export ALIBABA_CLOUD_CONNECT_TIMEOUT=30
export ALIBABA_CLOUD_READ_TIMEOUT=30

Or use command-line flags:

bash

aliyun kms <action> --connect-timeout 30 --read-timeout 30 ...

Recommended timeout values:

Connection timeout: 30 seconds
Read timeout: 30 seconds

Security Rules

Prohibited: Reading, printing, or displaying AK/SK values

Prohibited: Requiring users to directly input AK/SK in conversation
Sensitive Data Masking: Secret values returned by GetSecretValue are masked by default (e.g.,
***
), only output in plaintext when user explicitly requests

RAM Permission Requirements

Ensure the executing user has the following KMS permissions. For detailed policies, see references/ram-policies.md.

Minimum Permissions (Read-Only):

kms:DescribeSecret, kms:ListSecrets, kms:GetSecretValue, kms:ListSecretVersionIds, kms:GetSecretPolicy

Full Permissions (Read-Write):

kms:CreateSecret, kms:DeleteSecret, kms:UpdateSecret, kms:DescribeSecret, 
kms:ListSecrets, kms:GetSecretValue, kms:PutSecretValue, kms:ListSecretVersionIds,
kms:UpdateSecretVersionStage, kms:UpdateSecretRotationPolicy, kms:RotateSecret,
kms:RestoreSecret, kms:SetSecretPolicy, kms:GetSecretPolicy,
kms:ListKmsInstances, kms:ListKeys, kms:CreateKey

Core Workflows

1. Create Secret

Creating a secret requires obtaining the KMS instance ID and encryption key ID first, then executing the creation.

bash

# Step 1: Get KMS Instance ID
aliyun kms ListKmsInstances --PageNumber 1 --PageSize 10 --region <region-id> --user-agent AlibabaCloud-Agent-Skills
# → Extract KmsInstances.KmsInstance[0].KmsInstanceId

# Step 2: Get Encryption Key ID
aliyun kms ListKeys --Filters '[{"Key":"KeySpec","Values":["Aliyun_AES_256"]},{"Key":"DKMSInstanceId","Values":["<instance-id>"]}]' --PageNumber 1 --PageSize 10 --region <region-id> --user-agent AlibabaCloud-Agent-Skills
# → Extract Keys.Key[0].KeyId

# Step 3: Create Secret (requires DKMSInstanceId and EncryptionKeyId)
aliyun kms CreateSecret --SecretName "<secret-name>" --SecretData "<secret-value>" --VersionId "<version-id>" --EncryptionKeyId "<key-id>" --DKMSInstanceId "<instance-id>" --region <region-id> --user-agent AlibabaCloud-Agent-Skills

2. List Secrets

bash

aliyun kms ListSecrets --region <region-id> --user-agent AlibabaCloud-Agent-Skills

3. Get Secret Value

Security Policy:

If user does NOT explicitly request the secret value: Only provide the CLI command or Python code script. DO NOT execute.

If user explicitly requests to get/retrieve/show the secret value: Provide the command/script first, then execute after user confirms.

CLI Command:

bash

aliyun kms GetSecretValue --SecretName "<secret-name>" --region <region-id> --user-agent AlibabaCloud-Agent-Skills

Python SDK Example:

python

from alibabacloud_tea_openapi.client import Client as OpenApiClient
from alibabacloud_tea_openapi import models as open_api_models
from alibabacloud_credentials.client import Client as CredentialClient
from alibabacloud_tea_util import models as util_models

credential = CredentialClient()
config = open_api_models.Config(credential=credential)
config.endpoint = 'kms.<region-id>.aliyuncs.com'
client = OpenApiClient(config)

params = open_api_models.Params(
    action='GetSecretValue',
    version='2016-01-20',
    protocol='HTTPS',
    method='POST',
    auth_type='AK',
    style='RPC',
    pathname='/',
    req_body_type='json',
    body_type='json'
)

body = {'SecretName': '<secret-name>'}
runtime = util_models.RuntimeOptions()
request = open_api_models.OpenApiRequest(body=body)
response = client.call_api(params, request, runtime)
print(response.body)

Note:

Only execute the retrieval after user explicitly confirms

The secret value contains sensitive information that should be handled with care

Always remind user to execute in a secure environment (private terminal, no screen sharing, no logging)

4. Delete Secret

Pre-check before deletion (Safety Requirement):

Before force deleting a secret, always verify its existence and check if it's still in use:

bash

# Step 1: Describe the secret to verify existence and check metadata
aliyun kms DescribeSecret --SecretName "<secret-name>" --region <region-id> --user-agent AlibabaCloud-Agent-Skills
# → Check SecretName, CreateTime, and other metadata to confirm this is the correct secret

If DescribeSecret returns error (secret not found):

Stop and inform user: "Secret does not exist, no deletion needed"

If DescribeSecret succeeds:

Review the secret metadata
Confirm with user before proceeding with force deletion

bash

# Step 2: Force delete (immediate deletion, cannot be recovered)
aliyun kms DeleteSecret --SecretName "<secret-name>" --ForceDeleteWithoutRecovery true --region <region-id> --user-agent AlibabaCloud-Agent-Skills

Idempotency: If
Forbidden.ResourceNotFound
error is returned, it means the secret does not exist, treat as deletion successful and continue with subsequent operations.

5. Update Secret Value

bash

aliyun kms PutSecretValue --SecretName "<secret-name>" --SecretData "<new-secret-value>" --VersionId "<new-version-id>" --region <region-id> --user-agent AlibabaCloud-Agent-Skills

6. Describe Secret

bash

aliyun kms DescribeSecret --SecretName "<secret-name>" --region <region-id> --user-agent AlibabaCloud-Agent-Skills

7. List Secret Versions

bash

aliyun kms ListSecretVersionIds --SecretName "<secret-name>" --IncludeDeprecated true --region <region-id> --user-agent AlibabaCloud-Agent-Skills

8. Configure Rotation Policy

bash

aliyun kms UpdateSecretRotationPolicy --SecretName "<secret-name>" --EnableAutomaticRotation true --RotationInterval 7d --region <region-id> --user-agent AlibabaCloud-Agent-Skills

9. Restore Deleted Secret

bash

aliyun kms RestoreSecret --SecretName "<secret-name>" --region <region-id> --user-agent AlibabaCloud-Agent-Skills

Idempotency: If
Rejected.ResourceInUse
error is returned, it means the secret has been restored or was not deleted, treat as restore successful and continue with subsequent operations.
