# Secrets Management

Secure secrets management practices for CI/CD pipelines using Vault, AWS Secrets Manager, and other tools.

## Purpose

Implement secure secrets management in CI/CD pipelines without hardcoding sensitive information.

## Use this skill when

- Store API keys and credentials
- Manage database passwords
- Handle TLS certificates
- Rotate secrets automatically
- Implement least-privilege access

## Do not use this skill when

- You plan to hardcode secrets in source control
- You cannot secure access to the secrets backend
- You only need local development values without sharing

## Instructions

1. Identify secret types, owners, and rotation requirements.
2. Choose a secrets backend and access model.
3. Integrate CI/CD or runtime retrieval with least privilege.
4. Validate rotation and audit logging.

## Safety

- Never commit secrets to source control.
- Limit access and log secret usage for auditing.

## HashiCorp Vault Integration

### Setup Vault

```bash
# Start Vault dev server
vault server -dev

# Set environment
export VAULT_ADDR='http://127.0.0.1:8200'
export VAULT_TOKEN='root'

# Enable secrets engine
vault secrets enable -path=secret kv-v2

# Store secret
vault kv put secret/database/config username=admin password=secret
```

### GitHub Actions with Vault

```yaml
name: Deploy with Vault Secrets

on: [push]

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v4

    - name: Import Secrets from Vault
      uses: hashicorp/vault-action@v2
      with:
        url: https://vault.example.com:8200
        token: ${{ secrets.VAULT_TOKEN }}
        secrets: |
          secret/data/database username | DB_USERNAME ;
          secret/data/database password | DB_PASSWORD ;
          secret/data/api key | API_KEY

    - name: Use secrets
      run: |
        echo "Connecting to database as $DB_USERNAME"
        # Use $DB_PASSWORD, $API_KEY
```

### GitLab CI with Vault

```yaml
deploy:
  image: vault:latest
  before_script:
    - export VAULT_ADDR=https://vault.example.com:8200
    - export VAULT_TOKEN=$VAULT_TOKEN
    - apk add curl jq
  script:
    - |
      DB_PASSWORD=$(vault kv get -field=password secret/database/config)
      API_KEY=$(vault kv get -field=key secret/api/credentials)
      echo "Deploying with secrets..."
      # Use $DB_PASSWORD, $API_KEY
```

**Reference:** See `references/vault-setup.md`

## AWS Secrets Manager

### Store Secret

```bash
aws secretsmanager create-secret \
  --name production/database/password \
  --secret-string "super-secret-password"
```

### Retrieve in GitHub Actions

```yaml
- name: Configure AWS credentials
  uses: aws-actions/configure-aws-credentials@v4
  with:
    aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
    aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
    aws-region: us-west-2

- name: Get secret from AWS
  run: |
    SECRET=$(aws secretsmanager get-secret-value \
      --secret-id production/database/password \
      --query SecretString \
      --output text)
    echo "::add-mask::$SECRET"
    echo "DB_PASSWORD=$SECRET" >> $GITHUB_ENV

- name: Use secret
  run: |
    # Use $DB_PASSWORD
    ./deploy.sh
```

### Terraform with AWS Secrets Manager

```hcl
data "aws_secretsmanager_secret_version" "db_password" {
  secret_id = "production/database/password"
}

resource "aws_db_instance" "main" {
  allocated_storage    = 100
  engine              = "postgres"
  instance_class      = "db.t3.large"
  username            = "admin"
  password            = jsondecode(data.aws_secretsmanager_secret_version.db_password.secret_string)["password"]
}
```

## GitHub Secrets

### Organization/Repository Secrets

```yaml
- name: Use GitHub secret
  run: |
    echo "API Key: ${{ secrets.API_KEY }}"
    echo "Database URL: ${{ secrets.DATABASE_URL }}"
```

### Environment Secrets

```yaml
deploy:
  runs-on: ubuntu-latest
  environment: production
  steps:
  - name: Deploy
    run: |
      echo "Deploying with ${{ secrets.PROD_API_KEY }}"
```

**Reference:** See `references/github-secrets.md`

## GitLab CI/CD Variables

### Project Variables

```yaml
deploy:
  script:
    - echo "Deploying with $API_KEY"
    - echo "Database: $DATABASE_URL"
```

### Protected and Masked Variables
- Protected: Only available in protected branches
- Masked: Hidden in job logs
- File type: Stored as file

## Best Practices

1. **Never commit secrets** to Git
2. **Use different secrets** per environment
3. **Rotate secrets regularly**
4. **Implement least-privilege access**
5. **Enable audit logging**
6. **Use secret scanning** (GitGuardian, TruffleHog)
7. **Mask secrets in logs**
8. **Encrypt secrets at rest**
9. **Use short-lived tokens** when possible
10. **Document secret requirements**

## Secret Rotation

### Automated Rotation with AWS

```python
import boto3
import json

def lambda_handler(event, context):
    client = boto3.client('secretsmanager')

    # Get current secret
    response = client.get_secret_value(SecretId='my-secret')
    current_secret = json.loads(response['SecretString'])

    # Generate new password
    new_password = generate_strong_password()

    # Update database password
    update_database_password(new_password)

    # Update secret
    client.put_secret_value(
        SecretId='my-secret'
