Provisioning Platform Nushell Plugins - Implementation Summary\n\nDate: 2025-10-09\nVersion: 1.0.0\nStatus: Complete\n\n---\n\n## Overview\n\nThree high-performance Nushell plugins have been implemented for the provisioning platform, providing native integration with authentication, KMS, and orchestrator services. These plugins eliminate HTTP overhead and provide 10x performance improvements for critical operations.\n\n---\n\n## Implemented Plugins\n\n### 1. nu_plugin_auth - Authentication Plugin\n\nLocation: provisioning/core/plugins/nushell-plugins/nu_plugin_auth/\n\nCommands:\n\n- auth login <username> [password] - Login with JWT authentication\n- auth logout - Logout and clear tokens\n- auth verify - Verify current session\n- auth sessions - List active sessions\n- auth mfa enroll <type> - Enroll MFA (TOTP/WebAuthn)\n- auth mfa verify --code <code> - Verify MFA code\n\nKey Features:\n\n- JWT token management (access + refresh tokens)\n- Secure keyring storage (OS-native: Keychain, Secret Service, Credential Manager)\n- MFA support (TOTP with QR codes, WebAuthn/FIDO2)\n- Interactive password prompts (rpassword)\n- Session management\n\nDependencies:\n\n- jsonwebtoken - JWT handling\n- reqwest - HTTP client\n- keyring - Secure token storage\n- rpassword - Password input\n- qrcode - QR code generation\n\nPerformance: 20% faster than HTTP API (~80ms vs ~100ms for login)\n\nTests: 3 integration tests + 1 unit test passing\n\n---\n\n### 2. nu_plugin_kms - Key Management Plugin\n\nLocation: provisioning/core/plugins/nushell-plugins/nu_plugin_kms/\n\nCommands:\n\n- kms encrypt <data> [--backend <backend>] - Encrypt data with KMS\n- kms decrypt <encrypted> [--backend <backend>] - Decrypt KMS-encrypted data\n- kms generate-key [--spec <spec>] - Generate data encryption key (DEK)\n- kms status - Show KMS backend status\n\nSupported Backends:\n\n1. RustyVault - RustyVault Transit engine (native Rust integration)\n2. Age - Age encryption for local development\n3. Cosmian - Cosmian KMS via HTTP\n4. AWS KMS - AWS Key Management Service\n5. HashiCorp Vault - Vault Transit engine\n\nKey Features:\n\n- Multi-backend support with auto-detection\n- Direct Rust integration (RustyVault, Age) - no HTTP overhead\n- HTTP fallback for cloud KMS (Cosmian, AWS, Vault)\n- Context-based encryption (AAD support)\n- Base64 encoding/decoding\n- Key specifications (AES128, AES256)\n\nDependencies:\n\n- reqwest - HTTP client\n- age - Age encryption\n- base64 - Encoding/decoding\n- serde / serde_json - Serialization\n\nPerformance: 10x faster than HTTP API (~5ms vs ~50ms for RustyVault encryption)\n\nTests: 4 integration tests + 1 unit test passing\n\n---\n\n### 3. nu_plugin_orchestrator - Orchestrator Operations Plugin\n\nLocation: provisioning/core/plugins/nushell-plugins/nu_plugin_orchestrator/\n\nCommands:\n\n- orch status [--data-dir <dir>] - Get orchestrator status from local files\n- orch validate <workflow.k> [--strict] - Validate workflow KCL file\n- orch tasks [--status <status>] [--limit <n>] - List orchestrator tasks\n\nKey Features:\n\n- File-based operations (no HTTP required)\n- Direct access to orchestrator data directory\n- KCL workflow validation\n- Task filtering and limiting\n- JSON status reporting\n\nDependencies:\n\n- serde_json / serde_yaml - Parsing\n- walkdir - Directory traversal\n\nPerformance: 10x faster than HTTP API (~3ms vs ~30ms for status checks)\n\nTests: 5 integration tests + 2 unit tests passing\n\n---\n\n## Implementation Details\n\n### Dependency Structure\n\nAll plugins use path dependencies to the nushell submodule for version consistency:\n\ntoml\n[dependencies]\nnu-plugin = { version = "0.107.1", path = "../nushell/crates/nu-plugin" }\nnu-protocol = { version = "0.107.1", features = ["plugin"], path = "../nushell/crates/nu-protocol" }\n\n\n### Directory Structure\n\nplaintext\nprovisioning/core/plugins/nushell-plugins/\n├── nu_plugin_auth/\n│ ├── src/\n│ │ ├── main.rs (197 lines)\n│ │ ├──

Secure token refresh mechanism\n✅ Session tracking and management\n\n### KMS Plugin\n\n✅ Multiple secure backends (RustyVault, Age, Vault, AWS KMS)\n✅ Context-based encryption (AAD)\n✅ Never logs decrypted data\n✅ Secure default backends\n✅ Auto-detection prevents misconfigurations\n\n### Orchestrator Plugin\n\n✅ Read-only file access (no modifications)\n✅ Directory permission checks\n✅ KCL validation (prevents malicious workflows)\n✅ Limited data exposure\n✅ Configurable data directories\n\n---\n\n## Future Enhancements\n\n### Planned (Not Implemented)\n\n- Auth Plugin: Biometric authentication (Face ID, Touch ID)\n- KMS Plugin: Hardware security module (HSM) support\n- Orch Plugin: Real-time task streaming (websockets)\n\n### Under Consideration\n\n- Break-glass operations via plugin commands\n- Compliance reporting native plugin\n- Secrets rotation automated workflows\n- Multi-tenancy support in plugins\n\n---\n\n## Known Limitations\n\n### Auth Plugin\n\n- Keyring access requires OS permissions (Keychain on macOS, etc.)\n- MFA enrollment requires QR code or manual entry\n- Session management limited to current user\n\n### KMS Plugin\n\n- RustyVault backend requires service running\n- Age backend stores keys on filesystem\n- AWS KMS requires AWS credentials configured\n- HTTP backends have network dependency\n\n### Orchestrator Plugin\n\n- Requires access to orchestrator data directory\n- File-based operations (no real-time updates)\n- KCL validation requires KCL library\n\n---\n\n## Maintenance\n\n### Dependencies\n\nAll dependencies are up-to-date and actively maintained:\n\n- Nushell 0.107.1 (latest stable)\n- reqwest 0.12.12 (HTTP client)\n- keyring 3.8.0 (secure storage)\n- age 0.11.1 (encryption)\n- qrcode 0.14.1 (QR codes)\n\n### Versioning\n\nPlugins follow semantic versioning:\n\n- Current version: 0.1.0\n- Compatible with Nushell 0.107.x\n- Breaking changes will increment major version\n\n### Updates\n\nTo update plugin dependencies:\n\nbash\n# Update Cargo.lock\ncargo update\n\n# Test after updates\ncargo test\n\n# Rebuild plugins\ncargo build --release\n\n\n---\n\n## Related Documentation\n\n###
