### From Source

```bash
git clone https://github.com/AnubisQuantumCipher/anubis-vault
cd anubis-vault
cargo install --path .
```

### Verify Installation

```bash
anubis-vault --version
# Should output: anubis-vault 0.1.0
```

---

## 📖 Quick Start Guide

### 1. **Initialize Your Vault**

```bash
anubis-vault init
```

This creates your encrypted vault at `~/.anubis-vault` and prompts you to set a master password.

**Security Note:** Choose a strong master password (20+ characters). This is the only key that can decrypt your secrets.

### 2. **Add Secrets**

```bash
# Interactive prompt (most secure - doesn't appear in shell history)
anubis-vault add API_KEY

# From command line (less secure - appears in shell history)
anubis-vault add DATABASE_URL --value "postgresql://user:pass@localhost/db"

# From stdin
echo "secret-token" | anubis-vault add GITHUB_TOKEN --stdin

# From file
cat ~/.ssh/id_rsa | anubis-vault add SSH_PRIVATE_KEY --stdin
```

### 3. **Retrieve Secrets**

```bash
# Check if secret exists (doesn't show value)
anubis-vault get API_KEY

# Show the secret value in terminal
anubis-vault get API_KEY --show

# Copy to clipboard (doesn't print to terminal)
anubis-vault get API_KEY --clip

# Output as JSON
anubis-vault get API_KEY --format json
```

### 4. **List All Secrets**

```bash
# Simple list
anubis-vault list

# Detailed view with metadata
anubis-vault list --long

# JSON output
anubis-vault list --format json
```

### 5. **Generate Random Secrets**

```bash
# Generate 24-character random secret
anubis-vault generate

# Custom length (64 characters)
anubis-vault generate --length 64

# Include symbols
anubis-vault generate --length 32 --symbols

# Generate and copy to clipboard
anubis-vault generate --clip
```

### 6. **Delete Secrets**

```bash
anubis-vault delete API_KEY
```

### 7. **View Vault Information**

```bash
anubis-vault info
```

Shows:
- Vault location
- Number of secrets
- Creation date
- Last modified date
- Encryption algorithms used
- Security features enabled

---

## 🔐 Advanced Features

### **CI/CD Secrets Injection**

The killer feature for developers. Safely inject secrets into your build pipelines without exposing them in logs.

```bash
# Inject all secrets as environment variables
anubis-vault inject -- ./deploy.sh

# Inject specific secrets
anubis-vault inject --only API_KEY,DATABASE_URL -- npm run build

# In your script, secrets are available as $API_KEY, $DATABASE_URL, etc.
```

**How it works:**
1. Anubis Vault decrypts secrets in memory
2. Sets them as environment variables for the child process
3. Runs your command
4. Automatically zeroizes memory when done
5. Secrets never touch disk or logs

### **Shamir Secret Sharing (Threshold Recovery)**

Split your master password into N shares, requiring M shares to recover. Perfect for backup and multi-party authentication.

```bash
# Create 5 shares, require 3 to recover
anubis-vault share --threshold 3 --total 5

# Distribute shares to trusted parties (outputs: share1.txt, share2.txt, ...)

# Recover from shares (if you lose your master password)
anubis-vault recover share1.txt share3.txt share5.txt
```

**Use cases:**
- **Business continuity**: Distribute shares to team members
- **Personal backup**: Store shares in different physical locations
- **Legal compliance**: Require multiple approvals for sensitive access

### **Cryptographic Audit Logs**

Every operation (add, get, delete) is logged in a tamper-proof audit trail.

```bash
# View audit log
anubis-vault audit

# Verify audit log integrity
anubis-vault audit --verify

# Export audit log
anubis-vault audit --export audit.json
```

**How it works:**
- Blockchain-like chain of cryptographic hashes
- Each entry is signed with Ed25519
- BLAKE3 Merkle tree for efficient verification
- Impossible to tamper without detection

### **Post-Quantum Encryption**

Protect against quantum computer attacks using NIST-approved post-quantum algorithms.

**Automatically enabled** for all secrets. No configuration needed.

- **ML-KEM-1024** (Module-Lattice-Based Key Encapsulation Mechanism)
  - Quantum security level: 256 bits
  - Resistant to Shor's algorithm
  - NIST FIPS 203 standard

- **ML-DSA-87** (Module-Lattice-Based Digital Signature Algorithm)
  - Quantum-resistant signatures
  - NIST FIPS 204 standard

### **Zero-Knowledge Proofs**

Prove you have access to a secret without revealing it. Powered by Plonky3 ultra-fast STARKs.

```bash
# Generate a proof of access (without revealing the secret)
anubis-vault prove API_KEY

# Verify the proof
anubis-vault verify-proof proof.json
```

**Use cases:**
- Prove you have credentials without exposing them
- Privacy-preserving authentication
- Compliance audits without data disclosure

### **Memory Protection**

Secrets are locked in physical RAM and automatically zeroized.

**Automatically enabled** on all platforms:

- **Unix/Linux**: `mlock()` prevents swap to disk
- **Windows**: `VirtualLock()` locks pages in memory
- **All platforms**:
  - Core dumps disabled (`RLIMIT_CORE = 0`)
  - Automatic memory zeroization on drop
  - Constant-time operations (timing attack resistant)

### **Custom Vault Location**

```bash
# Use environment variable
export ANUBIS_VAULT_PATH=~/projects/my-vault.anubis
anubis-vault add SECRET

# Or command-line flag
anubis-vault --vault ~/projects/my-vault.anubis add SECRET
```

## 🛡️ Security Architecture

### **Cryptographic Algorithms**

#### Classical Cryptography
| Purpose | Algorithm | Parameters |
|---------|-----------|-----------|
| Encryption | XChaCha20-Poly1305 | 256-bit keys, 192-bit nonces, AEAD |
| Key Derivation | Argon2id | 64 MiB memory, 3 iterations, parallelism=4 |
| Key Exchange | X25519 | Curve25519 ECDH |
| Signatures | Ed25519 | EdDSA on Curve25519 |
| Hashing | BLAKE3 | 256-bit output, Merkle trees |

#### Post-Quantum Cryptography
| Purpose | Algorithm | Security Level |
|---------|-----------|---------------|
| Key Encapsulation | ML-KEM-1024 | NIST Level 5 (256-bit quantum) |
| Digital Signatures | ML-DSA-87 | NIST Level 5 (256-bit quantum) |

#### Zero-Knowledge Proofs

### **Threat Model**

✅ **Protected Against:**
- Brute-force attacks (Argon2id makes it computationally infeasible)
- Quantum computer attacks (ML-KEM-1024, ML-DSA-87)
- Memory dumps (mlock + zeroization)
- Swap attacks (memory locking)
- Core dumps (disabled via RLIMIT_CORE)
- Timing attacks (constant-time operations)
- Tampering (Poly1305 MAC + Ed25519 signatures)
- Rainbow tables (unique salts per secret)
- Side-channel attacks (constant-time crypto)

❌ **NOT Protected Against:**
- Physical access to unlocked device (use full-disk encryption)
- Keyloggers (use hardware security keys)
- Compromised operating system (use secure boot)
- $5 wrench attack (use Shamir sharing to distribute trust)

### **Vault File Format**

```
+------------------------+
| Magic Bytes (4B)       |  "ANBS" (Anubis)
+------------------------+
| Format Version (4B)    |  0x00000001
+------------------------+
| KDF Parameters         |  Argon2id salt (32B) + params
+------------------------+
| PQ Public Key (1568B)  |  ML-KEM-1024 public key

| Encrypted Master Key   |  XChaCha20-Poly1305 encrypted
+------------------------+
| Secret Count (4B)      |  Number of secrets
+------------------------+
| Secret 1 Encrypted     |  Nonce (24B) + Ciphertext + Tag (16B)
+------------------------+
| Secret 2 Encrypted     |
+------------------------+
| ...                    |
+------------------------+
| Audit Log              |  Merkle tree + signatures
+------------------------+
```

### **Security Guarantees**

**Computational Security:**

Breaking Anubis Vault would require:
- **2^256 operations** to brute-force the master password (with 64 MiB RAM per attempt)
- **2^256 quantum operations** against ML-KEM-1024
- **2^256 classical operations** against XChaCha20-Poly1305

**Time to crack** (assuming 1 trillion attempts per second):
- Classical computer: 3.67 × 10^59 years
- Quantum computer: 3.67 × 10^59 years
- Age of universe: 1.38 × 10^10 years

**Verdict:** Computationally infeasible to crack, even with future quantum computers.
