# SecretumVault
|
||||
|
||||
**Post-quantum cryptographic secrets management system for modern cloud infrastructure**
|
||||
|
||||
SecretumVault is a Rust-native secrets vault combining post-quantum cryptography (ML-KEM-768, ML-DSA-65) with classical crypto, multiple secrets engines, cedar-based policy authorization, and flexible storage backends.
|
||||
|
||||
## Features
|
||||
|
||||
### 🔐 Post-Quantum Cryptography
|
||||
- **ML-KEM-768**: Key encapsulation mechanism for key exchange
|
||||
- **ML-DSA-65**: Digital signatures with post-quantum resistance
|
||||
- **Hybrid mode**: Classical + PQC algorithms for future-proof security
|
||||
- **Multiple backends**: OpenSSL, AWS-LC, RustCrypto (feature-gated)
|
||||
|
||||
### 🔑 Secrets Engines
|
||||
- **KV Engine**: Versioned key-value storage with encryption at rest
|
||||
- **Transit Engine**: Encryption/decryption without storing plaintext
|
||||
- **PKI Engine**: Certificate authority with X.509 support
|
||||
- **Database Engine**: Dynamic credentials for PostgreSQL, MySQL, others
|
||||
- **Extensible**: Add custom engines via trait implementation
|
||||
|
||||
### 🛡️ Authorization & Policies
|
||||
- **Cedar Integration**: Attribute-based access control (ABAC)
|
||||
- **Fine-grained policies**: Context-aware decisions (IP, time, environment)
|
||||
- **Token management**: Lease-based credentials with automatic revocation
|
||||
- **Audit logging**: Full request/response audit trail
|
||||
|
||||
### 💾 Flexible Storage
|
||||
- **etcd**: Distributed KV store with high availability
|
||||
- **SurrealDB**: Document database with queries
|
||||
- **PostgreSQL**: Proven relational database
|
||||
- **Filesystem**: Development/testing
|
||||
- **Extensible**: Implement `StorageBackend` trait for any backend
|
||||
|
||||
### 🚀 Cloud Native
|
||||
- **Kubernetes-ready**: Native K8s deployments with RBAC
|
||||
- **Helm charts**: Production-ready templated deployments
|
||||
- **Docker**: Multi-stage builds for minimal images
|
||||
- **Prometheus metrics**: Built-in observability
|
||||
- **Structured logging**: JSON or human-readable format
|
||||
|
||||
### 🔄 Enterprise Ready
|
||||
- **TLS/mTLS**: Encrypted client communication
|
||||
- **Shamir Secret Sharing**: Multi-factor unsealing (2-of-3, 3-of-5, etc.)
|
||||
- **Auto-unseal**: AWS KMS, GCP Cloud KMS, Azure Key Vault (planned)
|
||||
- **High availability**: Multi-node clustering (planned)
|
||||
- **Replication**: Active-passive disaster recovery (planned)

## Quick Start
|
||||
|
||||
### Local Development with Docker Compose
|
||||
|
||||
```bash
|
||||
# Clone repository
|
||||
git clone https://github.com/secretumvault/secretumvault.git
|
||||
cd secretumvault
|
||||
|
||||
# Build and start
|
||||
docker build -t secretumvault:latest .
|
||||
docker-compose up -d
|
||||
|
||||
# Verify
|
||||
curl http://localhost:8200/v1/sys/health
|
||||
|
||||
# View logs
|
||||
docker-compose logs -f vault
|
||||
```
|
||||
|
||||
### Kubernetes Deployment
|
||||
|
||||
```bash
|
||||
# Deploy to cluster
|
||||
kubectl apply -f k8s/01-namespace.yaml
|
||||
kubectl apply -f k8s/02-configmap.yaml
|
||||
kubectl apply -f k8s/03-deployment.yaml
|
||||
kubectl apply -f k8s/04-service.yaml
|
||||
kubectl apply -f k8s/05-etcd.yaml
|
||||
|
||||
# Port-forward and access
|
||||
kubectl -n secretumvault port-forward svc/vault 8200:8200
|
||||
curl http://localhost:8200/v1/sys/health
|
||||
```
|
||||
|
||||
### Helm Installation
|
||||
|
||||
```bash
|
||||
# Install with default configuration
|
||||
helm install vault helm/ \
|
||||
--namespace secretumvault \
|
||||
--create-namespace
|
||||
|
||||
# Customize backends and engines
|
||||
helm install vault helm/ \
|
||||
--namespace secretumvault \
|
||||
--create-namespace \
|
||||
--set vault.config.storageBackend=postgresql \
|
||||
--set postgresql.enabled=true \
|
||||
--set vault.replicas=3
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Core Concepts
|
||||
|
||||
### Config-Driven Architecture
|
||||
|
||||
All components are selected via `svault.toml` configuration:
|
||||
|
||||
```toml
|
||||
[vault]
|
||||
crypto_backend = "openssl" # or "aws-lc", "rustcrypto"
|
||||
|
||||
[storage]
|
||||
backend = "etcd" # or "surrealdb", "postgresql"
|
||||
|
||||
[seal]
|
||||
seal_type = "shamir"
|
||||
threshold = 2
|
||||
shares = 3
|
||||
|
||||
[engines.kv]
|
||||
path = "secret/"
|
||||
versioned = true
|
||||
|
||||
[engines.transit]
|
||||
path = "transit/"
|
||||
```
|
||||
|
||||
No recompilation needed for backend changes—just update config.
|
||||
|
||||
### Registry Pattern
|
||||
|
||||
Type-safe backend selection using registry pattern:
|
||||
|
||||
```rust
|
||||
// CryptoRegistry dispatches config string to backend
|
||||
let crypto = CryptoRegistry::create(&config.vault.crypto_backend)?;
|
||||
|
||||
// StorageRegistry creates backend from config
|
||||
let storage = StorageRegistry::create(&config.storage)?;
|
||||
|
||||
// EngineRegistry mounts engines from [engines] section
|
||||
let engines = EngineRegistry::mount_engines(&config.engines)?;
|
||||
```
|
||||
|
||||
### Async/Await
|
||||
|
||||
Built on Tokio for high concurrency:
|
||||
- Non-blocking I/O for all storage operations
|
||||
- Efficient resource utilization
|
||||
- Scales to thousands of concurrent connections
|
||||
|
||||
### Token-Based Authentication
|
||||
|
||||
All API requests require `X-Vault-Token` header:
|
||||
|
||||
```bash
|
||||
curl -H "X-Vault-Token: $VAULT_TOKEN" \
|
||||
http://localhost:8200/v1/secret/data/myapp
|
||||
```
|
||||
|
||||
Tokens have:
|
||||
- TTL (time-to-live) with automatic expiration
|
||||
- Renewable for extended access
|
||||
- Revocable for immediate invalidation
|
||||
- Audit-logged for compliance

## Security
|
||||
|
||||
### Design Principles
|
||||
|
||||
- **Encryption at rest**: All secrets encrypted with master key
|
||||
- **Least privilege**: Cedar policies enforce fine-grained access
|
||||
- **Audit logging**: All operations logged and auditable
|
||||
- **Secure defaults**: Non-root execution, read-only filesystem, dropped capabilities
|
||||
- **Post-quantum ready**: Support for ML-KEM and ML-DSA
|
||||
|
||||
### Security Guidelines
|
||||
|
||||
See `docs/SECURITY.md` for:
|
||||
- Key management best practices
|
||||
- Unsealing strategy
|
||||
- Token security
|
||||
- TLS/mTLS setup
|
||||
- Audit log review
|
||||
- Vulnerability reporting
