Frequently asked questions
- Is QubKey free?
- Yes. QubKey is free and open-source under the MIT license. You can use, modify, and distribute it without restrictions. The source code is accessible for audit and community contribution.
- Is my data stored in the cloud?
- By default, no. QubKey is local-first: all your data stays on your device in encrypted .rkvey files. You keep full control — you can back up, move, or copy your vault files without depending on a cloud service. Optional cloud sync between your own devices may be enabled if you choose; it remains user-controlled and does not change the local-first design of the application.
- Can I share entries securely?
- Yes. From a vault entry you can create a temporary encrypted link (duration, max views, optional password) or send the entry to another QubKey account. Peer shares use X25519 key exchange and AES-256-GCM; recipients accept or dismiss in their inbox. You choose granted rights (read, modify, duplicate, temporary link, forward) and can revoke access. Optional attachments stay encrypted end to end.
- Is QubKey open-source?
- Yes. QubKey is released under the MIT license. The source code (Rust backend, Tauri bridge, React + TypeScript interface) is publicly available and can be audited by anyone. Standard cryptographic algorithms are used throughout, and the .rkvey format is documented for transparency.
- What platforms are supported?
- The QubKey 1.0.2 desktop app is available for macOS (Apple Silicon, DMG installer) and Windows 10/11 (NSIS and MSI installers, x64 and x86). Linux is in active development. The app is built with Tauri for native multi-platform performance, with system-specific integrations: Keychain on macOS and Credential Manager on Windows. Browser extensions are available for Chrome and Firefox on macOS and Windows. Each platform has its own extension package — macOS and Windows builds are not interchangeable.

The Problem
- Your data stored in the cloud without your control
- Risks of data leaks and security breaches
- Dependence on third-party services for your secrets
- Lack of transparency on encryption and security
- Inability to audit the source code
The QubKey Solution
- 100% local data with secure .rkvey format
- Optional cloud sync: enable it if you want, you keep full control
- AES-256-GCM and XChaCha20-Poly1305 encryption with Argon2id
- Open-source code (Rust + Tauri + React) fully auditable
- Zeroization of sensitive data in memory after use
- WAL (Write-Ahead Log) for crash recovery

Securityenhanced
Every aspect of QubKey is designed with security as the absolute priority.
AES-256-GCM Encryption
High levelHigh-level authenticated encryption (AEAD) with unique nonces per entry. XChaCha20-Poly1305 alternative available. Complete protection of data at rest.
Argon2id Derivation
Attack resistantSecure key derivation with calibrated parameters (p95 ≈ 200-300ms). Resistant to brute force and GPU attacks thanks to memory-hard design.
Zeroization
Memory protectionSecure erasure of sensitive data in memory after use. Keys, passphrases and secrets are automatically cleaned on vault lock.
Auto-lock
ConfigurableConfigurable automatic locking after inactivity (default: 5 minutes). Secure clipboard with automatic erasure after timeout.
.rkvey Format
Cryptographic signatureSecure vault files with "RKVE" cryptographic signature, B-Tree index for O(log n) search, WAL for crash recovery, intelligent LZ4 compression.
Audited and verified
MIT open-source code — auditable and transparent
BuiltinRustforuncompromisingsecurity
QubKey's core is written in Rust — a memory-safe language that eliminates entire classes of vulnerabilities by design. No null pointer exceptions, no buffer overflows, no data races. Combined with AES-256-GCM authenticated encryption, Argon2id key derivation, and automatic zeroization of secrets in memory, QubKey is engineered from the ground up for security-critical workloads.
