+# Using Envault in GitHub Actions for Secure CI/CD
+
+Managing environment variables and secrets in CI/CD pipelines is one of the most common security challenges in modern development. Hardcoding secrets in workflow files, committing .env files to repositories, or managing separate secret sets for each environment creates significant risks. Envault solves this by providing encrypted, version-controlled environment management that integrates seamlessly with GitHub Actions.
+
+## Why Envault for GitHub Actions?
+
+Traditional approaches to CI/CD secret management suffer from several problems:
+- Secrets scattered across repository secrets, workflow files, and .env files
+- No visibility into what changed between environments
+- Difficult rotation without breaking pipelines
+- No audit trail of who accessed or modified secrets
+
+Envault addresses these by:
+- Encrypting environment files with a single master key
+- Providing clear diff, sync, and rotation capabilities
+- Integrating with external secret stores (AWS SSM, HashiCorp Vault, etc.)
+- Maintaining an audit trail of all operations
+- Working completely offline on the free tier
+
+## Setting Up Envault for GitHub Actions
+
+### 1. Initialize Envault in Your Repository
+
+First, install Envault and initialize it in your project:
+
+```bash
+# Install from GitHub (since not yet on PyPI)
+pip install git+https://github.com/Coding-Dev-Tools/envault.git
+
+# Initialize Envault (creates .envault.yml)
+rh-envault init my-project
+
+# This creates a .envault.yml file with:
+# project: my-project
+# version: '1'
+# environments:
+#   - name: dev
+#     env_file: .env.dev
+#   - name: staging
+#     env_file: .env.staging
+#   - name: prod
+#     env_file: .env.prod
+```
+
+### 2. Configure Your Environments
+
+Create environment-specific .env files:
+
+```bash
+# .env.dev
+DATABASE_URL=postgresql://localhost/dev_db
+API_KEY=dev_key_123
+DEBUG=true
+
+# .env.staging  
+DATABASE_URL=postgresql://staging-db.company.com/staging_db
+API_KEY=staging_key_456
+DEBUG=false
+
+# .env.prod
+DATABASE_URL=postgresql://prod-db.company.com/prod_db
+API_KEY=prod_key_789
+DEBUG=false
+```
+
+### 3. Encrypt Your Environment Files
+
+Encrypt your environment files with a master key:
+
+```bash
+# First time encryption - you'll be prompted for a master key
+rh-envault encrypt
+
+# This creates encrypted versions:
+# .env.dev.enc
+# .env.staging.enc  
+# .env.prod.enc
+
+# Add the encrypted files to git (they're safe to commit)
+git add .env.*.enc
+git commit -m "Add encrypted environment files"
+
+# Add the master key to GitHub Secrets
+# Go to Settings > Secrets and variables > Actions > New repository secret
+# Name: ENVAULT_KEY
+# Value: [your master key from the encryption prompt]
+```
+
+## Using Envault in GitHub Actions Workflows
+
+Here's a complete GitHub Actions workflow that uses Envault for secure deployment:
+
+```yaml
+name: Deploy to Production
+
+on:
+  push:
+    branches: [ main ]
+
+jobs:
+  deploy:
+    runs-on: ubuntu-latest
+    environment: production
+
+    steps:
+    - uses: actions/checkout@v4
+
+    - name: Set up Python
+      uses: actions/setup-python@v5
+      with:
+        python-version: '3.10'
+
+    - name: Install Envault
+      run: |
+        pip install git+https://github.com/Coding-Dev-Tools/envault.git
+
+    - name: Decrypt Environment
+      env:
+        ENVAULT_KEY: ${{ secrets.ENVAULT_KEY }}
+      run: |
+        # Decrypt only the production environment
+        rh-envault decrypt prod --env-file .env.prod
+
+    - name: Verify Environment (Optional)
+      run: |
+        # Check that we have the right variables without showing values
+        rh-envault diff-files .env.prod.example .env.prod --fail-on-missing
+
+    - name: Deploy Application
+      env:
+        # Load variables from decrypted .env file
+        DATABASE_URL: ${{ env.DATABASE_URL }}
+        API_KEY: ${{ env.API_KEY }}
+        DEBUG: ${{ env.DEBUG }}
+      run: |
+        # Your deployment commands here
+        echo "Deploying to production..."
+        # Example: docker-compose up -d
+        # Example: ./deploy.sh
+
+    - name: Clean Up
+      if: always()
+      run: |
+        # Remove decrypted file for security
+        rm -f .env.prod
+```
+
+### Advanced: Using Envault with External Secret Stores
+
+For even better security, integrate with external secret stores like AWS SSM or HashiCorp Vault:
+
+```yaml
+# .envault.yml with AWS SSM integration
+project: my-app
+version: '1'
+
+environments:
+  - name: dev
+    env_file: .env.dev
+  - name: staging
+    env_file: .env.staging
+  - name: prod
+    env_file: .env.prod
+
+stores:
+  production-secrets:
+    type: aws-ssm
+    path_prefix: /my-app/prod
+    region: us-east-1
+
+audit_log_path: .envault-audit.log
+```
+
+Then in your workflow:
+
+```yaml
+- name: Sync from AWS SSM
+  env:
+    AWS_ACCESS_KEY_ID: ${{ secrets.AWS_ACCESS_KEY_ID }}
+    AWS_SECRET_ACCESS_KEY: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
+    ENVAULT_KEY: ${{ secrets.ENVAULT_KEY }}
+  run: |
+    # Pull latest secrets from AWS SSM, decrypt local env, then sync
+    rh-envault store get --store production-secrets --prefix /my-app/prod/
+    rh-envault decrypt prod
+    rh-envault sync production-secrets prod --strategy target_wins
+```
+
+## Best Practices for Envault in CI/CD
+
+1. **Use Environment Protection Rules**: Configure GitHub Environments with required reviewers and wait timers for production deployments.
+
+2. **Implement Drift Detection**: Add a step to check for configuration drift before deployment:
+   ```yaml
+   - name: Check for Drift
+     run: |
+       rh-envault diff staging prod --fail-on-missing
+   ```
+
+3. **Rotate Secrets Regularly**: Schedule regular secret rotation:
+   ```yaml
+   name: Monthly Secret Rotation
+
+   on:
+     schedule:
+       - cron: '0 0 1 * *'  # First day of every month
+
+   jobs:
+     rotate:
+       runs-on: ubuntu-latest
+       steps:
+         - uses: actions/checkout@v4
+         - name: Install Envault
+           run: pip install git+https://github.com/Coding-Dev-Tools/envault.git
+         - name: Rotate Production Secrets
+           env:
+             ENVAULT_KEY: ${{ secrets.ENVAULT_KEY }}
+           run: |
+             rh-envault rotate DB_PASSWORD --env prod
+             rh-encault rotate API_KEY --env prod
+             # Commit updated encrypted files
+             git config --local user.email "action@github.com"
+             git config --local user.name "GitHub Action"
+             git add .env.*.enc
+             git commit -m "chore: rotate production secrets [skip ci]"
+             git push
+   ```
+
+4. **Audit Access**: Regularly review the audit trail:
+   ```yaml
+   - name: Audit Check
+     run: |
+       rh-envault audit --limit 50
+   ```
+
+## Benefits of This Approach
+
+- **Security**: Secrets never exist in plaintext in your repository or logs
+- **Visibility**: Clear diffs show exactly what changed between environments
+- **Auditability**: Every encryption, decryption, sync, and rotation is logged
+- **Portability**: Works the same way locally and in CI/CD
+- **Flexibility**: Can integrate with external secret stores or work completely offline
+- **Team Friendly**: Configuration is stored in plaintext .envault.yml (safe to commit)
+
+## Getting Started
+
+1. Install Envault: `pip install git+https://github.com/Coding-Dev-Tools/envault.git`
+2. Initialize: `rh-envault init my-project`
+3. Create environment files (.env.dev, .env.staging, .env.prod)
+4. Encrypt: `rh-envault encrypt` (save the master key to GitHub Secrets)
+5. Add the workflow template above to `.github/workflows/deploy.yml`
+6. Add your master key to repository secrets as `ENVAULT_KEY`
+
+Envault transforms environment variable management from a security liability into a controlled, auditable process that gives you confidence in your deployments while maintaining the simplicity developers expect from CLI tools.
