Crate qudag_vault_core

Quantum-resistant password vault library for QuDAG.

This library provides a secure password management system using QuDAG’s quantum-resistant cryptographic primitives and DAG-based storage.

Features

• Quantum-Resistant Encryption: Uses ML-KEM (Kyber) for key encapsulation and ML-DSA (Dilithium) for digital signatures
• DAG-Based Storage: Stores secrets as nodes in a directed acyclic graph
• Memory Safety: Automatic zeroization of sensitive data
• Secure Key Derivation: Argon2id for password-based key derivation

Example

use qudag_vault_core::{Vault, VaultError};

// Create a new vault
let mut vault = Vault::create("vault.qdag", "master_password")?;

// Add a secret
vault.add_secret("email/work", "user@example.com", Some("password123"))?;

// Retrieve a secret
let secret = vault.get_secret("email/work")?;
println!("Username: {}", secret.username);

// Export the vault
vault.export("backup.qdag")?;
