Core Features
| Code | Feature Description |
|---|---|
| C1 | Password/Secret/API Key/Token Storage: Secure storage of sensitive data, including passwords, API keys, and tokens. |
| C2 | Encryption at Rest and in Transit: Ensures data is encrypted during storage and transmission to prevent unauthorized access. |
| C3 | Version Control and Secrets History/Log: Maintains a history of changes to secrets, providing rollback capabilities and accountability. |
| C4 | Automated/Triggered Rotation, Expiry, and Revocation: Supports automatic or on-demand rotation of secrets, as well as expiration and immediate revocation, to minimize risk from exposed or expired credentials. |
| C5 | Programmatic Access and Environment Integration: Provides API-based access for seamless integration with applications, automated systems, and specific deployment environments (e.g., CI/CD, containers). |
| C6 | Secure Retrieval Mechanism: Ensures secrets are retrieved securely when needed, preventing unauthorized or accidental exposure. |
Auxiliary Features
| Code | Feature Description |
|---|---|
| A1 | User Authentication and Access Control: Controls access to secrets, ensuring only authorized users or applications can retrieve them. |
| A2 | Policies: Supports policy-based management to enforce security and usage guidelines across secrets. |
| A3 | Audit Logging and Compliance: Tracks access, usage, and modifications to secrets for security, compliance, and incident response. |
| A4 | High Availability and Backup: Ensures secrets remain accessible with backup and redundancy mechanisms, critical for production environments. |
| A5 | Cross-Environment Sync and Notification Mechanisms: Ensures consistency and availability of secrets across multiple environments, essential for hybrid and multi-cloud setups. Includes mechanisms like webhooks, event streams, short TTLs, agent-based synchronization, and native cloud provider tools to propagate updates and maintain consistency. |
System Design and Architecture
1. Design the System Architecture
To build a modular and extensible password/secret management platform, we'll adopt a layered architecture with well-defined interfaces. This approach allows components to be developed, tested, and replaced independently without affecting the overall system.
Core Components
| ID | Component Name | Purpose | Functionality | Benefits |
|---|---|---|---|---|
| M1 | Storage Backend Interface Module | Abstracts the storage mechanism | - Defines a standard interface for CRUD (Create, Read, Update, Delete) operations on secrets. - Supports pluggable backends (e.g., in-memory, file system, databases, cloud services). |
- Allows swapping or upgrading storage backends without impacting other modules. - Enhances flexibility and scalability. |
| M2 | Encryption Module | Manages encryption and decryption | - Provides encryption at rest and in transit (C2). - Abstracts encryption algorithms and key management. - Ensures compliance with security standards. |
- Facilitates changes in encryption strategies without affecting other components. - Enhances security and compliance adherence. |
| M3 | Secret Management Module | Handles core secret management logic | - Implements operations for storing, retrieving, updating, and deleting secrets (C1). - Manages version control and maintains history logs (C3). - Interfaces with the Encryption Module for secure data handling. |
- Centralizes secret management logic. - Simplifies maintenance and future feature additions. |
| M4 | API Layer | Exposes functionalities to external systems | - Provides programmatic access through secure APIs (C5). - Ensures secure retrieval mechanisms with encryption in transit (C6). - Implements API versioning for backward compatibility. |
- Enables consistent integration with applications and systems. - Facilitates environment-specific deployments. |
| M5 | Authentication and Authorization Module | Controls access to the platform | - Authenticates users and systems (A1). - Manages access control policies. - Supports multiple authentication methods (e.g., API keys, OAuth). |
- Enhances security by ensuring only authorized access. - Provides a foundation for policies and compliance features. |
Component Interactions
- M4 (API Layer) receives requests and authenticates them via M5 (Authentication and Authorization Module).
- Upon successful authentication, requests are forwarded to M3 (Secret Management Module).
- M3 interacts with M2 (Encryption Module) to encrypt/decrypt secrets.
- Encrypted secrets are stored or retrieved through M1 (Storage Backend Interface Module).
2. Map Feature Dependencies
Understanding feature dependencies ensures that the architecture supports seamless integration and scalability.
