Instead of entering passwords, use QRS app to scan QR code displayed by supporting E2EE application. The QRS app will use your Master Key to wrap / unwrap Data Keys used by E2EE application to encrypt your data.

EASIER THAN PASSWORDS
Scanning QR codes is easier compared to entering passwords.

MORE SECURE THAN PASSWORDS
QRS uses randomly generated AES 256-bit KEK and DEK keys that cannot be brute-forced. Other encryption software often use keys derived from passwords that would usually have LOWER ENTROPY and can be brute-forced if password is weak. Even the strongest of manually managed passwords would have MUCH LESS entropy compared to random keys used in QRS.

NO RISK OF KEYLOGGERS
Keyloggers may steal your passwords while being typed. With QRS, keyloggers are of less concern b/c nothing is typed while unlocking (decrypting) your data.

STOP WORRYING WHERE AND HOW TO STORE YOUR KEYS
You may need to access your encrypted data from multiple places - from home, office, or that Cloud VM. No need to decide where to store your keys - QRS provides an easy way to store DEK keys together with your data (usually in the same file), authenticated and encrypted with Master Key. Master Key is securely stored in your phone protected by biometrics and Secure Enclave / Secure Element chips. Also, some Master Keys could be stored offline - completely offloaded from your phone - if used infrequently.

QUANTUM SAFE AES-256
QRS uses AES encryption with 256 bit keys, which is considered quantum safe.

AUTHENTICATED ENCRYPTION WITH ASSOCIATED DATA (AEAD)
QRS uses AES in GCM mode which provides the ability to cryptographically bind the metadata (Associated Data) describing the encrypted data. For example, Password Manager application might want to use 'website' and 'username' as Associated Data (AD) attributes. QRS uses AEAD extensively, for example, Client Application Name is a mandatory AD attribute. QRS also provides API for Client Applications to define custom AD attributes to be attached to wrapped DEK keys. Before unwrapping the DEK key, QRS application displays AD attributes to user and waits until user confirms the operation.

FREE AND OPEN SOURCE
QRS is Free and Open Source software with a permissive MIT licence. The source code will be published soon.

CROSS-PLATFORM
No more platform lock-in! QRS uses modern cross-platform C#/.NET stack and so it runs on IOS, Android, Windows, macOS, and Linux. Switching mobile platforms by Backing up your Master Key on Android and restoring it on IOS, or vice-versa, is super easy!

NO CLOUD ACCOUNTS
Having Apple, Google or Microsoft account is NOT required to use QRS.

NOTHING IS STORED SERVER-SIDE
There is NO risk of server-side data loss.

WHAT SOFTWARE IS USING QRS ENCRYPTION?

VAULT - ENCRYPTING FILES AND FOLDERS INTO .VAULT FILES
Cross-platform VAULT application (Desktop and CLI) to encrypt arbitrary files and folders (Windows, macOS, Linux, CLI)

PASSWORD MANAGER
Cross-platform Password Manager (Windows, macOS, Linux coming soon)

PROCESS LAUNCHER
Command Line utility that uses encrypted YAML config to set environment variables then launch the process.

YOUR APPLICATION
QRS encryption could be integrated into any web, mobile, desktop or command line application. Learn more at QRID.COM!
