## Overview

Abir-Guard is a production-grade, quantum-resistant encryption vault built for AI agent memory and sensitive data protection. It implements NIST-standard Post-Quantum Cryptography (PQC) to defend against **Harvest Now, Decrypt Later (HNDL)** attacks — where adversaries collect encrypted data today to decrypt once quantum computers become powerful enough.

**Three-phase implementation:**
1. **Bedrock** — Hybrid KEM, AES-256-GCM, zero-copy memory, MCP server, LangChain/CrewAI SDKs
2. **Hardware & Security** — ML-DSA-65 signatures, SHAMIR secret sharing, Argon2id KDF, HSM/TPM
3. **Ecosystem & Hardening** — Key revocation (CRL), auto rotation, FIPS 140-3 mode, differential privacy, remote attestation, Go SDK

**Written in three languages** for maximum portability: Python for AI agent integration, Rust for high-performance cryptography, Go for infrastructure tooling, and JavaScript for browser and Node.js environments.

---

## Use Cases

### 1. Protecting AI Agent API Keys
AI agents frequently handle API keys, OAuth tokens, and service credentials. Abir-Guard encrypts these at rest and in memory, ensuring no raw secrets leak through memory dumps, swap files, or process inspection.

```python
vault.store("gpt_agent", b"OPENAI_API_KEY=sk-...")
```

### 2. Secure Agent-to-Agent Communication
Use the MCP JSON-RPC server as a local encryption gateway. Agents send plaintext to the server; encryption happens locally without exposing data to LLM context or consuming tokens.

### 3. Regulatory Compliance (FIPS 140-3)
Enable strict FIPS mode to enforce NIST-approved algorithms only, block non-compliant fallbacks, enforce minimum key lengths, and maintain audit trails for compliance audits.

```python
from abir_guard.fips_mode import FIPSEncryptor
fips = FIPSEncryptor()
result = fips.encrypt(data, key)
```

### 4. Multi-Party Key Recovery (SHAMIR)
Split master secrets across trusted parties. A 3-of-5 SHAMIR scheme means any three administrators can reconstruct the master key, but fewer than three learn nothing.

```bash
./target/release/abir-guard shamir-split "master-key" -t 3 -n 5
```

### 5. Breach Detection via Canary Keys
Plant honeypot keys that alert when accessed. If an attacker compromises the vault and uses a canary key, you know immediately.

```python
canary_id = vault.add_canary()
if vault.check_canary():
    alert_security_team("Breach detected!")
```

### 6. Automatic Key Lifecycle Management
Configure time-based or usage-based key rotation. Keys automatically expire after N operations or N hours, reducing the window of exposure from compromised keys.

```python
rotation_manager.register_key("agent-1", max_operations=1000)
```

### 7. Remote Attestation for Decryption Gates
Before decrypting sensitive data, verify the runtime environment is untampered — checking binary integrity, environment variables, and memory canaries.

```python
from abir_guard.attestation import AttestationVerifier
verifier = AttestationVerifier()
proof = IntegrityProof()
proof.compute(challenge)
if not verifier.verify_proof(proof.to_dict()):
    raise Exception("Runtime integrity check failed")
```

### 8. Post-Quantum Digital Signatures (ML-DSA-65)
Sign and verify data integrity using NIST FIPS 204 ML-DSA-65 — post-quantum secure, tamper-evident, non-repudiation guarantees.

```rust
let keypair = ml_dsa::generate_keypair().unwrap();
let signature = ml_dsa::sign(b"agent-memory", &keypair.signing_key).unwrap();
```

## Python SDK Guide

### Basic Vault Operations

```python
from abir_guard import Vault

vault = Vault()

# Generate keypair for an agent
pub, sec = vault.generate_keypair("finance_agent")

# Encrypt sensitive data
ct = vault.store("finance_agent", b"API_KEY=sk-abc123xyz")

# Decrypt data
plaintext = vault.retrieve("finance_agent", ct)
# → b"API_KEY=sk-abc123xyz"

# Auto-generate keys on first use
ct = vault.store("new_agent", b"data")  # keypair created automatically

# List and delete keys
vault.list_keypairs()        # ['finance_agent', 'new_agent']
vault.remove_keypair("new_agent")
```

### Phase 3 Features

```python
# Key Revocation (CRL)
from abir_guard.revocation import RevocationList, RevocationReason
crl = RevocationList()
crl.revoke("compromised-key", RevocationReason.COMPROMISED, "admin", "Key leaked")
crl.is_revoked("compromised-key")  # True

# Automatic Key Rotation
from abir_guard.rotation import KeyRotationManager
mgr = KeyRotationManager(default_max_operations=1000)
mgr.register_key("agent-1", max_operations=500)
mgr.record_usage("agent-1", "encrypt")
mgr.needs_rotation("agent-1")  # False (under limit)

# FIPS 140-3 Compliance Mode

## Quantum Readiness

### What "Quantum-Ready" Means for Abir-Guard

| Threat | Mitigation | Status |
|---|---|---|
| **Harvest Now, Decrypt Later** | ML-KEM-1024 key encapsulation (NIST FIPS 203) | Production Ready |
| **Quantum Key Extraction** | AES-256-GCM with 256-bit keys (Grover-resistant) | Production |
| **Signature Forgery (Shor's)** | ML-DSA-65 digital signatures (NIST FIPS 204) | Production |
| **Side-Channel Quantum Attacks** | Differential privacy entropy + constant-time comparison | Production |
| **Memory Scraping** | Zero-copy memory policy + explicit key zeroization | Production |
| **Future Quantum Break** | Hybrid KEM (ML-KEM + X25519) — both must break | Production |

### Current Quantum Status

- **AES-256-GCM**: Quantum-safe. Grover's algorithm reduces effective strength to 128-bit, still secure.
- **ML-DSA-65**: Post-quantum signatures deployed and tested. 3309-byte signatures, constant-time operations.
- **ML-KEM-1024**: Production-ready. Implemented in Python via `pqcrypto` (PQClean-backed) and Rust via `ml-kem` crate (pure Rust). Full keygen, encapsulation, and decapsulation roundtrip verified.
- **SHAMIR + Argon2id**: Classical but quantum-safe for their use cases (threshold sharing, key derivation).

### Mission Alignment 🇮🇳🌍

This project aligns with and supports:

- **🇮🇳 Indian Quantum Mission** — India's National Quantum Mission (NQM) aims to develop quantum technologies for communication, computing, and sensing. Abir-Guard provides NIST-standard post-quantum cryptography to safeguard India's quantum infrastructure against Harvest Now, Decrypt Later threats.
- **🌍 Global Quantum Mission** — Aligns with the worldwide transition to post-quantum cryptography as mandated by NIST, ENISA, and national cybersecurity agencies. Abir-Guard implements NIST FIPS 203 (ML-KEM) and FIPS 204 (ML-DSA) for quantum-resilient data protection.
- **🇮🇳🌍 Indian AI Mission** — Supports India's AI sovereignty initiative by providing quantum-secure memory vaults for AI agents, ensuring API keys, model weights, and agent memory remain protected against future quantum attacks. Built in India, for the world.

### After Quantum Breakthrough

1. All ML-KEM-1024 backends are production-ready — no additional setup needed
2. Python uses `pqcrypto` (PQClean-backed) for native ML-KEM-1024
3. Rust uses `ml-kem` crate (pure Rust, zero dependencies)
4. Existing hybrid keys remain valid during transition
