What is Encryption?
The Encryption skill is a specialized module designed for AI coding agents to implement and maintain high-security standards across various platforms. By leveraging this component within the Openclaw Skills ecosystem, developers can ensure that their applications use modern, authenticated encryption (AEAD) and robust password hashing algorithms like Argon2id. It acts as both an execution engine for CLI-based encryption and a technical guide for avoiding common cryptographic pitfalls.
This skill bridges the gap between raw cryptographic theory and practical application. It provides specific implementation strategies for Node.js, Python, and Go, alongside mobile-specific wrappers for iOS and Android. Whether you are managing key rotations, configuring TLS for infrastructure, or auditing legacy code for security holes, this skill provides the necessary rules and tools to keep data safe.
Encryption Use Cases
- Encrypting sensitive files, database fields, or application storage.
- Implementing secure password hashing using Argon2 or bcrypt with high cost factors.
- Managing cryptographic key rotation, derivation, and secure storage.
- Configuring TLS and certificate auto-renewal for cloud infrastructure.
- Auditing source code to detect hardcoded keys or deprecated algorithms.
How Encryption Works
- The AI agent analyzes the security requirement, such as securing a user database or a local file.
- It selects the optimal algorithm based on the Openclaw Skills recommendation matrix, prioritizing AEAD modes like AES-256-GCM.
- For file operations, the skill utilizes CLI tools like age or GPG to perform encryption and decryption.
- For application code, it generates secure snippets for password hashing or JWT signing using RS256.
- The agent runs a post-implementation audit using the built-in checklist to ensure no secrets are leaked in logs or git history.
Encryption Setup
To integrate this security module into your Openclaw Skills workflow, ensure your environment has the required CLI utilities installed. Modern encryption often relies on the age tool for simplicity and speed.
# Install age for modern file encryption
brew install age
# Or install GPG for legacy support
brew install gnupg
Ensure that environment variables are used for key management instead of hardcoding secrets within your configuration files.
Encryption Data Schema & Taxonomy
The skill organizes cryptographic metadata and implementation patterns across several specialized documentation layers. This ensures that the AI agent follows the correct protocol for each platform.
| Component | Purpose | Supported Standards |
|---|---|---|
| Symmetric | Data at rest | AES-256-GCM, ChaCha20-Poly1305 |
| Asymmetric | Key exchange | RSA-4096+OAEP, Ed25519 |
| Hashing | Credentials | Argon2id, bcrypt (cost ≥ 12) |
| KDF | Key derivation | PBKDF2 (≥ 600k iterations) |
| Infrastructure | Transport security | TLS 1.2, TLS 1.3, mTLS |
Platform-specific patterns are stored in patterns.md, mobile.md, and infra.md to maintain a clean separation of concerns.
Encryption Advanced Features
- Support for Envelope Encryption using external providers like AWS KMS or HashiCorp Vault.
- Automated detection of weak random number generators like Math.random() in favor of CSPRNG.
- Native mobile integration for iOS Keychain and Android EncryptedSharedPreferences.
- Certificate pinning and mTLS configuration for service-to-service communication.
- Constant-time comparison utilities to protect against side-channel timing attacks.
