Zero-Knowledge Secrets

ZenoVault

The Source of Truth for Your Secrets

Enterprise-grade secrets management with zero-knowledge architecture and multi-cloud synchronization. ZenoVault cannot access your secrets without explicit human intervention through a distributed unsealing ceremony. Automatically sync to AWS, GCP, and Azure.

Architecture

True Zero-Knowledge Design

Unlike traditional vaults, ZenoVault is architecturally incapable of accessing your secrets. The service starts sealed and requires a distributed ceremony to unseal.

Sealed State Default

ZenoVault starts sealed on every restart. Data operations are rejected until the unsealing ceremony completes.

Distributed Unsealing

Uses Shamir's Secret Sharing to distribute trust. No single person can access secrets alone.

Memory-Protected Keys

Root key exists only in encrypted RAM using memguard with mlock. Never touches disk.

Automatic Resealing

On restart, the vault automatically reseals with complete memory wipe. No persistent key exposure.

Security

Four-Layer Envelope Encryption

Every secret is protected by multiple layers of encryption, each with its own key hierarchy.

Layer 1

Root Key (RK)

256-bit AES key, RAM only, reconstructed via Shamir's Secret Sharing

Layer 2

Key Encryption Key (KEK)

Per-vault key, encrypted by Root Key. Vault isolation guaranteed.

Layer 3

Data Encryption Key (DEK)

Per-secret-version key, encrypted by KEK. Built-in key rotation.

Layer 4

Ciphertext

Actual secret encrypted with AES-256-GCM using the DEK

New Feature

Multi-Cloud Secret Synchronization

Automatically sync your secrets to AWS Secrets Manager, GCP Secret Manager, and Azure Key Vault. Maintain ZenoVault as your source of truth while enabling seamless cloud-native integrations.

AWS Secrets Manager

IAM role or static credentials authentication with automatic region replication and seamless integration.

GCP Secret Manager

Workload Identity or service account key with project-level organization and native GCP integration.

Azure Key Vault

Managed Identity or service principal with vault-level isolation and Azure-native secret management.

Smart Sync Features

Auto-sync on update, rate limiting & quotas, retry with exponential backoff, and Prometheus metrics.

Integration

Kubernetes Native

First-class Kubernetes integration with a custom operator and CRDs for automatic secret synchronization.

ZenoVault Operator

Kubernetes controller for automatic secret synchronization using the RemoteSecret CRD.

OIDC Authentication

Native K8s service account tokens validated via OIDC. No credential files needed.

Auto-Sync

Secrets automatically synced to Kubernetes native Secrets. Configurable refresh intervals.

Multi-Environment

Create isolated vaults for production, staging, and development. Each with its own KEK.
