key is generated for each encryption operation +2. **Data Encryption**: The actual data is encrypted using AES-GCM with the DEK +3. **Key Encryption**: The DEK is encrypted using NHN Cloud SKM +4. **Storage**: Both encrypted data and encrypted DEK are stored together + +### Key Rotation Support +- **Automatic Tracking**: Tracks key versions returned by NHN Cloud SKM API +- **Version Management**: Stores key version information for proper decryption +- **Seamless Rotation**: Supports key rotation without data migration + +### Supported Mechanisms +- **Direct Encryption** (Legacy): For backward compatibility with existing encrypted data +- **Envelope Encryption** (Default): For new encryption operations, supports unlimited data size + +## Configuration Examples + +### Using Environment Variables +```bash +export NHN_CLOUD_SKM_APP_KEY="your-app-key" +export NHN_CLOUD_SKM_KEY_ID="your-key-id" +export NHN_CLOUD_SKM_USER_ACCESS_KEY_ID="your-access-key-id" +export

in NHN Cloud SKM console +- User account with SKM access permissions +- Authentication method configured (one or more): + - IPv4 address authentication + - MAC address authentication + - Client certificate authentication + +## Security Considerations + +### Authentication +- Uses NHN Cloud user credentials for API authentication +- Supports optional MAC address filtering for enhanced security + +### Encryption Details +- **Data Encryption**: AES-256-GCM for actual data +- **Key Protection**: NHN Cloud SKM symmetric key encryption +- **Integrity**: Built-in integrity verification through AES-GCM + +### Best Practices +- Rotate NHN Cloud user credentials regularly +- Use different keys for different environments (dev/staging/production) +- Configure appropriate authentication methods (IPv4/MAC/Certificate) +- Monitor key usage and access through NHN Cloud SKM console +- Use approval workflows for production key management + +## Compatibility + +### OpenBao Integration +This wrapper is designed for use with OpenBao auto-unseal functionality: + +```hcl +seal "nhncloudskm" { + app_key = "your-app-key" + key_id = "your-key-id" + user_access_key_id = "your-access-key-id" + user_secret_access_key = "your-secret-access-key" + endpoint = "https://api-keymanager.nhncloudservice.com" + mac_address = "your-mac-address" # Optional +} +``` + +### Backward Compatibility +- Supports decryption of data encrypted with direct encryption method +- New encryptions use envelope encryption by default +- Seamless migration path for existing encrypted data + +## Error Handling + +Common error scenarios and solutions: + +| Error | Cause | Solution | +|-------|-------|----------| +| `app key is required` | Missing app key configuration | Set
